Hi,

with Intel building dedicated GPUs now, it is possible to have an Intel GPU
inside a non-x86 system.

This patch is the minimum I need to get rendering on B580 to work on
TalosII, so that is the "works for me" configuration. Presumably we can
enable more architectures here. Not sure if i915 can maybe also be useful
as well, it refuses to configure so I've left it x86 only for now.
