I decided the "beforedepend: bootstrap" attempt at a fix was wrong,
because it led to always using the precompiled/processed versions of the
generated files on every pass (boostrap tools, world, crossbuilding),
and I think that wasn't the intention. I discovered (by accident,
actually) that there was no need to run the bootstap target at all as
long as m4 got built before lex during the bootstrap-tools stage, so
that's the fix I applied, and it was sufficient to build current and
stable-10 on a stable-8 build host.
I suppose at this point the bootstrap target, and all the pre-generated
files it copies, could be deleted. Unless they're serving some other
purpose I'm not aware of, like maybe some folks have a need to run that
target manually.
