Glibc defines __LT_SPINLOCK_INIT on HPPA as "1".  Another constant hods
the initializer; __LT_SPINLOCK_INIT is a predicate.

Carlos has since changed that in his HPPA patches for linuxthreads,
which haven't been accepted upstream, because they didn't like how he
was doing it, I think.

All libnss-db needs to do is remove the first half of the #if.  This
isn't a bug in glibc, since that's a private copy of libc-lock.h.
