Thanks for this new version. However, you still didn't reply to me
about what happens when HOST_ARCH != ARCH. The vboot-utils Makefile
seems to have some logic to use Qemu in that case. Do you understand
what it does exactly with Qemu, and that we won't have a problem by
having HOST_ARCH != ARCH ?

Thanks!

Thomas
