It would be nice if releng would be able to namespace their private
flags properly instead of cluttering the global flag namespace with
stuff you aren't allowed to touch and reserving the two useful flag
names here.

In fact, I don't even understand why the flags aren't hard-masked if
you're not supposed to set them. Of course, that would require some
minimal effort of setting stage building stuff to unmask the flag...
