Bug#789395: libdrm-nouveau2: pushbuf.c not found

[Ilia Mirkin <imirkin@alum.mit.edu>]

I believe that Mesa 11.1.1 as well as the upcoming (not yet released)
11.0.9 releases will resolve this problem. At least I was able to
(rarely) hit an issue with stk before, and am no longer after the
patch I pushed (a more complete version of the one I had previously
provided).

Please retest with Mesa 11.1.1 (or 11.0.9 when it comes out in a few
days probably) and let me know if you still have issues. [No idea when
Debian packages will be available for these, but hopefully...
eventually?]
