I figured out how to fix it and will be posting a patch later this week.
but a function like:
static void
darwin_patch_builtin (int fncode)
{
   tree fn = built_in_decls[fncode];
   const char *newname;
   if (!fn)
     return;

   sym = DECL_ASSEMBLER_NAME (fn);
   newname = alloca (IDENTIFIER_LENGTH (sym)+9);
   strcpy (newname, IDENTIFIER_POINTER (sym));
   strcat (newname, "$LDBL128");
   sym = get_identifier (newname);
   SET_DECL_ASSEMBLER_NAME (fn, sym);

   fn = implicit_built_in_decls[fncode];
   if (fn)
     SET_DECL_ASSEMBLER_NAME (fn, sym);
}

Will do it.


And then go through all the builtins which need to be fixed.
