gallium in mesa 7.5

[Julien Cristau <jcristau@debian.org>]

Hi,

this builds gallium in all configurations, which is probably not what we
want.  It seems only the swx11 configs actually build a libGL, the rest
has empty GALLIUM_STATE_TRACKERS_DIRS.

Michel, in which configurations does it make sense to build gallium, and
what should we build?
Should we ship any of it?  If so, what and in what package?

Thanks,
Julien
