    gallium: fix build on GNU/kFreeBSD


I am currently playing WoW with my HD4670 (AGP), and I am noticing that various
textures are being rendered incorrectly when viewed beyond a certain distance.
However, as I approach the badly rendered area, all of the artifacts disappear!
It's as if my character is surrounded by an invisible bubble, and everything
within the bubble becomes correctly rendered. (The visual effect reminds me of
the "Genesis wave" demonstration video from "Star Trek: The Wrath of Khan" - if
that means anything to anyone...;-).)

This problem is not visible with the HD4890 on my 64 bit machine.

I have attached a couple of screenshots showing the problem.
