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.
