Different meanings and procedures for bootstrapping.  I am trying to ensure somebody
without a previous M3 distribution can check one out, then build it with a binary
only of the release compiler (e.g., via cminstall).  I have not been using upgrade.sh,
because it alters your /usr/local/cm3 in place, overlaying the original.  This is not
very handy for repeated experiments, when I have to keep recreating it.  It will build
though, with the dependencies in question.

Instead, I have been using do-pkg.sh and do-cm3-*.sh.  These, by default, use -override,
which builds everything in the cvs checkout and leaves /usr/local/cm3 alone.  In this case,
trying to build a compiler first has no m3core or libm3 available, while building a
library that depends on the newer compiler also fails.  The separation I did allows this
by getting code that an older compiler won't build into a separate package, where it can
be done later.  Unfortunately, it also means you can't just ship later, after all goes
well.
