Afaict pretty much all of the binaries "disabled" with this patch are
intel specific. As such please throw a configure switch (enabled by
default) rather than the current build_x86 heuristic, otherwise things
are bound to get very ugly pretty quickly.

The libpciaccess will be a pain although libdrm-intel should be
relatively easier. I doubt people will have major issues if the former
requirement stays forever.
