linuxthreads.old: Fix segfault when pthread_mutex_unlock() called against unlocked NORMAL mutex.
Althought, it is undefined behavior, there is no reason for segfault.
Program received signal SIGSEGV, Segmentation fault.
__pthread_unlock (lock=lock@entry=0x804b03c <lock+16>)
at libpthread/linuxthreads.old/spinlock.c:231
231 (&lock->__status, oldstatus, (long)(thr->p_nextlock) & ~1L))
It occurs only on platforms which has HAS_COMPARE_AND_SWAP defined.
Restore glibc commit fbaf6e72d6 "spinlock.c (__pthread_unlock): Don't crash if
called for an untaken mutex." behavior, broken later by commit 4ad1d0cfbf.
