Hmm, do old toolchains know about these cores?

Looking around in gcc.git, it seems like they were added:

a53/a57 in 4.8 for aarch64 / 4.9 for arm
a72 in 5.1 for aarch64/arm

So we need to ensure the older gcc versions cannot be selected when
these variants are selected. We possibly also need to do something for
external toolchains.
