2. Linuxthreads sysdep changes.
This patch represents the minor changes required in linuxthreads sysdeps to
accomodate for hppa's special lock requirements (e.g. A structure instead of
an integer).
The changes are minor and require that __LT_SPINLOCK_INIT no longer be used in
a macro comparison since it's now a structure. A different define
(__LT_INITIALIZER_NOT_ZERO) is used to indicate an architecture that does not
initialize a lock to zero.
Cheers,
Carlos.

* linuxthreads/sysdeps/pthread/bits/libc-lock.h:
Use __LT_INITIALIZER_NOT_ZERO.
* linuxthreads/sysdeps/pthread/bits/pthreadtypes.h:
spinlock in struct _pthread_fastlock is __atomic_lock_t.
