All of the mesa demos work with and without llvm.

I don't actually have piglit - it was always a pain with cmake to get it
to build on my old 32bit lfs with xorg/mesa installed under home.
I do now have a new 64bit clfs build with everything in normal places -
so maybe I'll give it a go on that - but I don't know how to use it as such.
Even though it's "new" clfs uses gcc 4.6.3 so on there g++ is actually
too old to build your tree - without changing some friends .... to
friends class ...
I don't know when I'll get time to learn piglit but for now here's
working and not nexuiz.
