This came from pkgsrc-wip. It had -fvisibility=hidden for all Mesa
packages by default. I made it exclude glut because -fvisibility=hidden
broke glut completely.
Side note; the "fix" committed by tron looks bogus to me. Removing a
flag doesn't make any sense if it isn't added anwhere.
Perhaps something like this patch will work?
