* sysdeps/generic/ldsodefs.h (DL_LOOKUP_GSCOPE_LOCK): New definition.
	* elf/dl-runtime.c (_dl_fixup, _dl_profile_fixup): Or in
	DL_LOOKUP_GSCOPE_LOCK into flags after THREAD_GSCOPE_SET_FLAG ().
	* elf/dl-sym.c (do_sym): Likewise.
	* include/link.h (struct link_map): Add l_serial field.
	* elf/dl-object.c (_dl_new_object): Initialize l_serial.
	* elf/dl-lookup.c (add_dependency): Add flags argument.
	Remember map->l_serial, if DL_LOOKUP_GSCOPE_LOCK is among
	flags, use THREAD_GSCOPE_RESET_FLAG before and
	THREAD_GSCOPE_SET_FLAG after
	__rtld_lock_lock_recursive (GL(dl_load_lock)) to avoid deadlock.
	Don't dereference map until it has been found on some list.
	If map->l_serial changed, return -1.
