patch from fedora

Can you test the attached patch? It's taken from fedora but it has the stuff that is already in gentoo and a test that might be 6.1+ only removed.

Thanks Kostadin! The linked patch fixes the build on ppc. Though I had to rip out the vulkan parts of the patch to make it cleanly apply on ppc.
