Since libiberty provides xatexit (for reasons explained elsewhere),
clearly Nr 1 is not correct.

Ideally I think we'd have system.h do Nr 3 when needed, but at present
that would cause problems with canadian crosses since we do not link
genfoo against libiberty.  So, failing that, I don't see any harm in
restricting this sort of fix to fixinc.
