Doesn't work because of the handful of places that #include <mach/*>
with a common name, like irqs.h or debug-macro.S.

That would still put them into a globally visible location since we
do gcc -I arch/arm/plat-${PLAT}/include.

I think we're not likely to get there any time soon. Most platforms in fact
