Yes I'll change this.

I didn't earlier because it failed when I tried it, but it looks like I
had QEMU=.../qemu-system-aarch64 in my environment variables, overriding
the default qemu-system-arm (32-bit only). "qemu-system-aarch64 -cpu max"
doesn't boot 32-bit code, but "qemu-system-aarch64 -cpu cortex-a15" does.
Anyway, without explicitly setting the wrong QEMU, "-cpu max" works for
32-bit.

Thanks,
Jean
