* While we want to exclude include/GL (because we
get the whole directory) we also exclude include/GLES2
which gets picked up in newer Mesa code
* Add a slash on the end of the grep to make sure we omit
*just* include/GL
* rtasm symbol collision fix.
There is older Mesa rtasm code, and newer Gallium3D
rtasm code. There are colliding symbols only seen when
you link Mesa and Gallium into the same shared library.
This diff makes Mesa use the Gallium3D rtasm code.
* Mesa target architecture fix.
This ensures the generated Mesa binaries work under
Pentium or higher processors. Fix for #8318
