We can discover our x,y coordinate in the core mesh with an
mfspr instruction, multiply y by the core mesh width, and have
the core number without needing to ask the kernel.
The macro pthread_cleanup_push_defer_np in pthread.h has a misaligned
line continuation marker. This marker was previously aligned, but
recent changes have moved it out of alignment. This change realigns
the marker. This also reduces the diff against the hppa version of
pthread.h where the marker is aligned.
Updates the hppa-specific pthread.h from the generic version.
After this update the only difference between the generic
version and the hppa version is the footer protected by the
_PTHREAD_H_HPPA_ guard.

[BZ #14652]
When a thread waiting in pthread_cond_wait with a PI mutex is
cancelled after it has returned successfully from the futex syscall
but just before async cancellation is disabled, it enters its
cancellation handler with the mutex held and simply calling a
mutex_lock again will result in a deadlock. Hence, it is necessary to
see if the thread owns the lock and try to lock it only if it doesn't.
db-symbols.awk relies on English-language readelf output to find the
beginning of the symbol table, so force the locale.
Without this change, "make check" fails in non-English locales:
