I don't see how changes from 1999 (which is when "${BMAKE} bootstrap"
disappeared from Makefile.inc1) have anything to do with the fact that
the most recent import of flex (in 2013) added a bootstrap target that
wasn't there previously, and that nothing nowadays invokes it. I'm also
not really clear on why the latest import added a bootstrap target that
never runs and doesn't seem to be needed (now that I've added a
dependency so that the new m4 is built before the new lex).
