I first tried to cross compile binutils-final from x86_64 but it failed
because all the mes packages don't support powerpc yet. Then I tried
emulating an aarch64 machine to cross compile binutils-final and that
failed at make-boot0. I think we can assume that binutils-final (and the
other -final packages) aren't going to be cross compiled.

,@(if might be cleaner to look at, but ,@(match makes it easier to
make change later without worrying about nested if statements. Which
hopefully shouldn't be an issue anyway for binutils-final.
