Hi Dmitry,

It should be limited to the platforms where the hardware is available,
so that coverage builds aren't needlessly spending cycles building
stuff that can't possibly ever be used. Also if it is limited to
ARM, then we can't have an ARM bug like this one mask the x86_64
allyesconfig build from uncovering possible errors that we really
care about seeing.
