It was an env var to disable the multitexture extension, but the other
drivers aren't checking for it anymore. It doesn't seem necessary, so
I'll just ignore it now.

I ran glean with indirect rendering and the texCombine test still fails
(it's the only one that fails). We haven't merged any recent Mesa changes
from the trunk yet, so I don't know if there's a fix already. I'm
attaching the output from glean.
