Yes, scons is designed to work in one pass rather than two and always
does any configure stuff up front before building targets; clean is
just another target. This is good for build consistency, because what
you need to clean may depend on configure options.

This is the carnivorous config bug, exactly. You could have left the -c off 
the second call to scons and would have seen the same misbehavior.  I suspect
it's due to some bug in the scons configure extensions.
