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.

A simple variant on time crossed with intel_gpu_top to estimate the
amount of GPU activity during a program's execution time.
The resource usage (sys+user, i.e. CPU %) is for the child, but the
GPU measure is global. Hmm.
