You know, it would be a lot cleaner if sdbout took care of this
itself.  That is, global_decl it gets called at the same time
as for everyone else, but it puts the decls that it wants to
deferr on a queue.  These would be emitted in debug->finish.

Careful that you get this queue registered as a GC root.

You probably want to use a VARRAY like so:

  varray_type sdb_deferred_globals;

  VARRAY_TREE_INIT (sdb_deferred_globals, 8, "sdb_deferred_globals");
  ggc_add_tree_varray_root (&sdb_deferred_globals, 1);

  if (do it later)
    VARRAY_PUSH_TREE (sdb_deferred_globals, decl);
