[PATCH mesa] Include search for non pkg-config libtalloc.

[Trevor Woerner]

From: Trevor Woerner <twoerner at gmail.com>

Change search for libtalloc so a build which includes it in a
non pkg-config'ized form will succeed.

My system includes libtalloc and libtalloc-devel in a way that is not
pkg-config'ized. I'm hoping this or something like this will be accepted
so my build can succeed.
