* 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.
