Assume LLL_LOCK_INITIALIZER is 0
Since hppa is not an outlier anymore regarding LLL_LOCK_INITIALIZER value, we can now assume it 0 for all architectures. Checked on a build for all major ABIs. * nptl/nptl-init.c (__pthread_initialize_minimal_internal): Remove initialization for LLL_LOCK_INITIALIZER different than 0. * nptl/old_pthread_cond_broadcast.c (__pthread_cond_broadcast_2_0): Assume LLL_LOCK_INITIALIZER being 0. * nptl/old_pthread_cond_signal.c (__pthread_cond_signal_2_0): Likewise. * nptl/old_pthread_cond_timedwait.c (__pthread_cond_timedwait_2_0): Likewise. * nptl/old_pthread_cond_wait.c (__pthread_cond_wait_2_0): Likewise. * sysdeps/nptl/libc-lockP.h (__libc_lock_define_initialized): Likewise.
