Bootstrapping (or not) always is a tradeoff.

To provide faster builds for users of the default lang/gcc and
older branches, which should be rather stable, I am defaulting
those to not bootstrap.  This is based on feedback I received
over the years in favor of faster build times.  

Users can always opt to enable that option if they desire so, 
of course.
