I think there is only one call that matters here, that's the one
in assemble_start_function.  I believe that there is a small bug
in notice_global_symbol.  It seems to me the function of this
routine is just to set appropriate values for first_global_object_name
and weak_global_object_name in a given translation unit.  The way
the code is written first_global_object_name or weak_global_object_name
can set several times until both get set.  I don't know if this matters
but we certainly don't get the "first" global object name saved in
first_global_object_name.s

Possibly, you are correct that we are accidently picking an external
symbol for the first global object name and this is causing the duplication
in constructor names.
