Hmm... a part of me wonders whether it'd make more sense to rename the
64-bit one to powerpc64, to match e.g. arm/arm64. But it's probably
not worth the breakage for existing users.
Equally, I doubt there are enough people who care about 32-bit little
endian to warrant a powerpc32le config (and if there are, they can
always add them in a follow up).

So this looks good as-is, thanks!
