Don't link to libGL at compile time
Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it easier to cross-arch compile on Linux and add support for OpenGL ES in the future. Users still have to supply their own libSDL2 for cross-arch compiling on Linux. But now the user does not have to re-install libgl1-mesa-dev package for i386 or amd64 on Debian when switching between compiling ioquake3 for x86 and x86_64.
