I removed libGL.a and re-ran configure (the stock one from mplayer) and OpenGL
on my system was not detected. I applied my patch that changes -lGL to -lGLU
and OpenGL was detected and mplayer did run with accelerated OpenGL.
You were correct in that the libGL.a on my system was the one from Mesa and
that is why OpenGL did not work properly (it was unaccellerated)
Perhaps there could be an additional test that if detection of OpenGL fails
when using libGL it could be tried again with libGLU and see if that works?
That way it will only fall back to libGLU if needed?
