IIRC, we had issues with getting drm.7 without using GNU make.   And the 
build of libdrm_radeon was failing without using gcc.  I'll revert back 
to Studio and get you the failures since its been a while having made 
the switch.

We had disabled tests because of parfait failures which is part of our 
build process.  But I think we should be able to enable it now since we 
have an updated version of parfait that we are building with.
