I don't particularly like it either, for the same reason.  Also tcomplex
is bombing for me when linked against a shared libstdc++ :-(  I'm
currently rebuilding gcc using a binutils without the section symbol hacks
to see whether the problem disappears.

The other hack is to change global section syms back to local at some
point during a final link.  We need to treat them as global long enough
to resolve to the kept section, but fudge back to local before they find
their way into the dynamic symbol table.
