(Finish_group::set_saw_undefined): New function. (Finish_group::set_blocker): New function. * symtab.h (class Symbol_table): Change saw_undefined to return size_t. Change saw_undefined_ field to size_t. * target-select.cc (Set_target_once::do_run_once): New function. (Target_selector::Target_selector): Initialize set_target_once_ field. Don't initialize lock_ and initialize_lock_ fields. (Target_selector::instantiate_target): Rewrite. (Target_selector::set_target): New function. * target-select.h (class Set_target_once): Define.
