The symbol was moved using scripts/move-symbol-to-libc.py. This change also turns __pthread_once into a compatibility symbol because after the call_once move, an internal call to __pthread_once can be used. This an adjustment to __libc_once: Outside libc (e.g., in nscd), it has to call pthread_once. With __pthread_once as a compatibility symbol, it is no longer to add a new GLIBC_2.34 version after the move from libpthread, and this commit removes the new __pthread_once@@GLIBC_2.34 version.
