    debug/97718 - fix abstract origin references after last change

    The change to clear the external_die_map slot after creating
    the concrete instance DIE broke abstract origin processing which
    tried to make sure to have those point to the early abstract instance
    and not the concrete instance.  The following restores this by
    eventually following the abstract origin link in the concrete instance.

            point to the abstract instance.
