Comment # 11 on bug 84140 from demon

Here's the Arch's PKGBUILD:
https://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/mesa

Modified PKGBUILD I use is attached. As you can see, I'm building only r600
driver, and I don't build opencl stuff (so I don't have mesa-opencl package
installed which contains `gallium-pipe/pipe_r600.so`).
