Apps that use clutter (or OpenGL) currently crash on ARM with messages like:

LLVM ERROR: Not supported instr %R0<def> = LEApcrel <cp#1>, pred:14, pred:%nore

e.g. glxgears, totem


This is because mesa is built with llvmpipe for ARM, but llvm for ARM is broken at the moment.

ppc* already disables llvmpipe within mesa.spec for similar reasons. Can ARM be added to this exception case too?

That way the non-llvm swrast will be built, and apps that use clutter/OpenGL can run (albeit slowly!).
