description:
Changes to the emitted makefiles that actually build the objects:

1) Always do a make clean before building objects in any directory.  This
   is wasteful, but there's really no other simple way to cope with the
   fact that the compilation settings (e.g. CFLAGS) appropriate for the
   non-crunched build of a program may not be appropriate for the crunched
   build.  If the objdir magic in make didn't rely upon the presence of an
   "obj" or "obj.${MACHINE}" symlink, we could abuse it to handle this but
   unfortunately, it does.

2) Override $DBG to cause object files to be built with -Os.  We can't emit
   "DBG?=" into the generated makefile because of order-of-inclusion issues
   with the system Makefiles; the result would be that the default setting
   (currently -O2) would always be used instead of -Os.  If you're crunching,
   you almost certainly are doing it to get a smaller executable (!) so -Os
   is almost certainly appropriate for you.
