Comment # 5 on bug 101832 from Emil Velikov

Right, so I may have misread the Xorg.log, but at least the AVX binaries will
not have unresolved symbols, props to
https://patchwork.freedesktop.org/patch/168170/

Possible symbol collision comes to mind, but I'm not working on either SWR or
radeonsi :-\

Tim, can you please have a look?
