qemu_binary is determined like this:

    qemu_binary = qemu_target_binary(data)
    if qemu_binary == "qemu-allarch":
        qemu_binary = "qemuwrapper"

So it will fall back to qemuwrapper if the recipe inherits allarch.

Besides, at this point it's a theoretical problem, right? We don't
even have a suitable allarch recipe to play with and see where things
work and where they don't, and whether the fallback to qemuwrapper
works correctly. If such recipe appears, we can look at the issue
again.
