u_atomic.h should probably check for a supported compiler; Jeremy, does
the attached patch produce an understandable error instead of a link
error?

In terms of a solution, Jeremy, you could implement PPC assembly for
the few primitives available there.  Looks easy for someone who knows
PPC well.  There's a comment in that file that mentions a mutex-based
implementation... but then I don't see one.

Looks like there's some dri radeon code which is using the gcc
primitives directly instead of through the gallium wrapper.  I'm not
familiar enough w/ it to know if that's correct or not (.. anyway,
you're probably not building dri/radeon on OS X, right?).
