Enable compilation on non-Intel, non-DRM systems.

A few of the tools can be performed post-mortem from a different system,
so it is useful to be able to compile those tools on those foreign
systems. Obviously, any program to interact with the PCI device or talk
to GEM will fail on a non-Intel system.
