A light just went on. We could use a "exclude system archive" flag -
dont' export symbols originating from libraries in /usr/local/lib/* or
/usr/lib/* ( and possibly the gcc lib dir as well - although I think
that is a spec thing, as it's gcc's decision to have the library given a
certain name).

Whaddya think?
