cortex-a9 sounds fine. It'd be cool if we verified those binaries run on a cortex-a8 and a cortex-a15, too. It'd be very, very strange if they didn't, but hey, catching very, very strange problems is what release testing is for, right? :)

At least for now, I do think we should constrain "ARM is a supported target" to mean armv7. For purposes of testing, armv6 is effectively a different target.
