sandbox should be built with the host toolchain, right? The one it is
complaining about is the amd64-host aarch64 toolchain, which we don't
want or need yet.

The grub part (and the cross toolchains) needs more work, but we don't
need it for sandbox, or at least the sandbox tests seem to pass
without it. Are you wanting to run qemu on arm64 to boot grub?

I believe I've taken a reasonable stab at a good starting point for
this work. Do you agree?
