There's a surprising amount of assumption out there around what arm*
means (or doing wildcard matches liberally). I'm glad (from the point of
view of a distribution bootstrap) that we don't have to worry about that
aspect of getting AArch64 support up and running. The directory name is
just that - a name - and unimportant. I like aarch64 from the point of
view of distinguishing "this is not ARM, no, it's not just an extension,
and no it's not just two numbers different or wider regs", but it seems
fairly inevitable that it's going to be arch/arm64. The main thing is
that we understand this isn't like i686->x86_64.
