Hmmm, OK. While that makes it a bit more difficult for people wanting to
install reverse operating bootloaders I don't think it changes the basic
premise - if 3.11 doesn't have USB enabled then the change in
mkamsboot/rbutil gets reverted and a new release of mkamsboot/rbutil is
done at the same time.
