Don't link against SDL2main (#265)

Problem: Since the removal of !_IRR_OPENGL_USE_EXTPOINTER_ we require some quite recent
symbols to compile the legacy GL driver. (*) Since the previous commit we prefer including
them via SDL but those are sometimes too old.

(*) This was in fact always a problem since USE_EXTPOINTER is the default.
    I guess people just had recent enough headers usually.

 IrrlichtMt version 1.9
 ======================
 
-The Irrlicht Engine is an open source realtime 3D engine written in C++.
+IrrlichtMt is the 3D engine of [Minetest](https://github.com/minetest).
-
+It is based on the [Irrlicht Engine](https://irrlicht.sourceforge.io/) but is now developed independently.
-This is a fork by the [Minetest](https://github.com/minetest) developers that was stripped-down and customized specifically for use in Minetest.
 It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.

-Configuration is by default "Release"
-But you can also chose "Debug" if you want Irrlicht with Debug information.
-Static builds are possible but you have to additionally set the _IRR_STATIC_LIB_ define in the application when linking to a static Irrlicht.lib

-If you wish to compile Irrlicht for Win32-gcc you have several choices.
-
-1. You can work from within a MinGW shell.
-Go to the folder source/Irrlicht and run the Makefile with:
-make win32 
-Examples can be build by going into the folder of the example (for example examples/01.HelloWorld) and running the Makefile with:
-make all_win32
-
-2. Use the Code::Blocks IDE
-There is a project file called Irrlicht-gcc.cbp in source/Irrlicht to compile just the engine.
-Be sure to select a Windows target like "Win32 - release - accurate math - dll"
-
-There is also Code::Blocks workspace file in the examples folder called BuildAllExamples.workspace
-Again be sure to select a Windows target like "Win32 - release - accurate math - dll"
-This workspace allows you to compile the engine together with all examples and tools.

-Checklist for Irrlicht developers doing releases.
-
-Note: Generally the more platforms, compilers, settings you can test the better. Ask for help for platforms which you don't own.
-
-- PRE-BUILD TESTS:
-- - Run tests in the tests folder
-- - Compile and run examples.
-- - Compile and run the tools. Note that some tools are in the buildall-examples VS project files on Windows, 
-    but on Linux command line you have to compile them individually.
-
-- VERSION UPDATES:
-- - check IRRLICHT_SDK_VERSION (in IrrCompileConfig.h)
-- - check version number in the Makefile
-- - update readme.txt (version number, supported compilers)
-- - Add new release information (date+version-number) in changes.txt
-- - go through folders if other .txt files still make sense (things change and updating those files tends to be forgotten)
-
-- DOCUMENTATION UPDATES:
-- - run makedocumentation.sh in scripts\doc\irrlicht
-- - run maketutorial.sh in scripts\doc\irrlicht (commit changed tutorial.html's)
-
-- BUILDING THE RELEASE
-  (TBD - should we still release dll's? Newer and older VS builds are no longer compatible anyway)
-- - run a clean build for buildAllExamples in the examples folder with the 
-    target compiler for 32-bit and for release (old VS compiler - so far VS2010)
-- - when possible compile the dll for MinGW on Windows (in release and with -s for smaller size)
-- - when possible compile the dll for 64 bit (again with Visual Studio and release)
-- - create a target directory, like irrlicht-1.8.1 for example
-- - svn export to the target directory
-- - copy the subfolders of doctemp into the doc folder of the target directory
-    careful, this should only be one(!) subfolder (we ended up with copies before, maybe Windows/Linux builds use different names?)
-- - copy all .exe files (except test.exe) from bin\Win32-VisualStudio (.pdb's are not necessary)
-- - copy Irrlicht.dll from bin\Win32-visualstudio 
-- - copy the files in lib\Win32-visualstudio
-- - copy Irrlicht.dll from bin\Win64-VisualStudio 
-- - copy the files in lib\Win64-visualstudio 
-- - copy Irrlicht.dll from bin\Win32-gcc 
-- - copy the files in lib\Win32-gcc
-- - remove the tests folder
-- - remove scripts folder (if the release comes with docs, if you do a release 
-without docs for smaller filesizes then the script folder has to stay in).
-- - create a zip file 
-- - figure out how to fix unix access right for shell-scripts in the zip file (my 
-trick so far is: unzip in Linux, set +x for all .sh files, zip again)
-
-RELEASING:
-- - upload the zip-file somewhere, then download it again on all platforms and do 
-  another quick test with that file (do examples still run, can you compile)
-- - give the link to the zip out on the mailinglist for others to look at
-- - Upload new documentation (the content of doc/html) to: web.sourceforge.net 
-  (sftp protocol, user and passwd are your sourceforge account, the folder 
-  might not be shown - but you can still cd into it!):
-  /home/project-web/i/ir/irrlicht/htdocs 
-  Best create first a folder with a new name, copy stuff in there, test (just 
-  check the website), rename old folder and give new folder the "docu" name. 
-  Then you can delete the old folder if you want.
-- - upload the zip by logging in to sourceforge and using the "Files" menu (needs 
-	admin privileges and it's the 'Files' menu between 'Summary' and 'Reviews'). 
-	The target is in one of the Irrlicht SDK subfolders. Then click the "i" beside 
-	the file and "select all" to make it the active download.
-- - write a forum post, tell everyone in facebook, reddit, your friends...
-- - login to wordpress at http://irrlicht.sourceforge.net/wp-login.php, update the 
-	downloads section and write a release post.

-The Irrlicht Engine SDK version 1.9
-==========================================================================
-
-  Welcome to the Irrlicht Engine SDK.
-
-  Content of this file:
-
-  1. Directory Structure Overview
-  2. How To Start
-  3. Requirements
-  4. Release Notes
-  5. License
-  6. Contact

-==========================================================================
-1. Directory Structure Overview
-==========================================================================
-
-  You will find some directories after uncompressing the archive of the
-  SDK. These are:
-
-  \bin         The compiled library Irrlicht.DLL and some compiled demo
-               and example applications, just start them to see the
-               Irrlicht Engine in action. Windows only.
-  \doc         Documentation of the Irrlicht Engine.
-  \examples    Examples and tutorials showing how to use the engine with
-               C++.
-  \include     Header files to include when programming with the engine.
-  \lib         Libs to link with your programs when using the engine.
-  \media       Graphics and sound resources for the demo applications and
-               examples.
-  \source      The source code of the Irrlicht Engine. This code is
-               not needed to develop applications with the engine,
-               but it is included to enable recompilation and
-               debugging, if necessary.
-  \tools       Useful tools (with sourcecode) for the engine.
-
-
-
-==========================================================================
-2. How to start
-==========================================================================
-
-  To see the engine in action in Windows, just go to the \bin\Win32-VisualStudio
-  directory, and start some applications. There should also be an
-  application named Demo.exe which should show the most
-  interesting features of Irrlicht.
-
-  To start developing own applications and games with the engine take
-  a look at the 01.HelloWorld example in the \examples directory.
-  There is also a .html file with a tutorial which should be
-  easily comprehensible.
-
-  The Irrlicht Engine is a static lib under linux. A precompiled version can be
-  generated from the sources using the Makefile in source/Irrlicht. Run 'make' in 
-  that subfolder. After this you should be able to 'make' all
-  example applications in /examples by calling the buildAllExamples script. You 
-  can run the examples then from the bin folder.
-
-  It is also possible to use Irrlicht as shared object
-  (libIrrlicht.so.versionNumber). Use the proper makefile target for this by
-  running 'make sharedlib' in the source folder. See the Makefile for details.
-
-  For OSX you can find an XCode project file in source/Irrlicht/MacOSX. This will
-  build the libIrrlicht.a library necessary to create the apps.
-
-==========================================================================
-3. Requirements
-==========================================================================
-
-  You can use one of the following compilers/IDEs to develop applications
-  with Irrlicht or recompile the engine. However, other compilers/IDEs may
-  work as well, we simply didn't test them.
-
-  * gcc 4.x
-  * Visual Studio 2010(10.0)-2013(12.0)
-  * Code::Blocks (& gcc or visual studio toolkit)
-  
-  If you ever want to (re)compile the engine yourself (which means you don't
-  want to use the precompiled version) you need the following:
-
-  * Windows:
-	* Needed: PlatformSDK (which usually comes with all IDEs, download
-			it separately for MSVC Express 2005)
-	* Optional: DirectX SDK, for D3D9 support
-	* Optional: DirectX SDK prior to May 2006, for D3D8 support
-
-  * Linux:
-	* Needed: XServer with include files
-	* Optional: OpenGL headers and libraries (libGL.so) for OpenGL support
-		GLX +
-		XF86VidMode [package x11proto-xf86vidmode-dev] or XRandr
-		(X11 support libraries, the latter two for fullscreen mode)
-
-  * OSX:
-	* Needed: XCode and Cocoa framework
-	* Needed: OpenGL headers and libraries
-
-==========================================================================
-4. Release Notes
-==========================================================================
-
-  Informations about changes in this new version of the engine can be
-  found in changes.txt.
-
-  Please note that the textures, 3D models and levels are copyright
-  by their authors and not covered by the Irrlicht engine license.
-
-==========================================================================
-5. License
-==========================================================================
-
-  The license of the Irrlicht Engine is based on the zlib/libpng license.
-  Even though this license does not require you to mention that you are
-  using the Irrlicht Engine in your product, an acknowledgement
-  would be highly appreciated.
-
-  Please note that the Irrlicht Engine is based in part on the work of
-  the Independent JPEG Group, the zlib, and libpng. This means that if you use
-  the Irrlicht Engine in your product, you must acknowledge somewhere
-  in your documentation that you've used the IJG code and libpng. It would
-  also be nice to mention that you use the Irrlicht Engine and the zlib.
-  See the README files in the jpeglib and the zlib for
-  further informations.
