Looks like both 3.8 and 3.5 versions of LLVM are getting pulled in, and LLVM
3.5 wasn't safe against this yet.

Is your self-built radeonsi_dri.so available in /usr/lib/x86_64-linux-gnu/dri/
as well? That's where the Xorg glx module looks for the DRI drivers. I suspect
it's failing to load radeonsi_dri.so from there and falling back to
swrast_dri.so, which is linked against LLVM 3.5.
