This is complicated because of a second compilation of nptl/pthread_mutex_lock.c via nptl/pthread_mutex_cond_lock.c. PTHREAD_MUTEX_VERSIONS is introduced to suppress symbol versions in that case. The symbols __pthread_mutex_lock, __pthread_mutex_unlock, __pthread_mutex_init, __pthread_mutex_destroy, pthread_mutex_lock, pthread_mutex_unlock, pthread_mutex_init, pthread_mutex_destroy have been moved using scripts/move-symbol-to-libc.py.
