Commit 0055c6a introduced a new preConfigure hook that sets the right
qmake path. Unfortunately the mkDerivation attributes of fmit override
the whole configurePhase, so this hook isn't run at all.
This doesn't fix the build of fmit, because it's unable to find
GL/glu.h. However I think this isn't an issue of the fmit package but
rather rooted in propagating the wrong output paths from freeglut.
