Currently:

  apt-get build-dep qemu

Is broken on arm64, that's a fairly serious failure because it means you
can't rebuild QEMU binaries. I'm not sure how the buildd daemons deal with
that? Unless there is another documented way of bringing in build
dependencies.

Personally I'd be happy if we packaged cross compilers for all of
Debian's architectures but that is a personal wish. However being able
to build binaries for the other "first tier" release architectures seems
like a reasonable stepping stone. The current breakage is caused by
s390x firmware but we have firmware for the other architectures as well.

Sure, I can only test what I have hardware for so for my first patch I
aimed low.
