Maybe (and I realise other ports do) but in some ways it gives the worst
of both worlds.  libsupc++ and libstdc++ will end up eating chunks of the
small data area without getting any real benefit from it.

A configure-time option is likely to be more convenient for folks who
use -G0 because you don't have to coerce every build system to add it
on the command line.  And it wouldn't penalise those who want to use
the usual -G8.
