Remove.
* sysdeps/unix/sysv/linux/sparc/sparc32/pthread_barrier_wait.c
(struct sparc_pthread_barrier): Remove.
(pthread_barrier_wait): Use union sparc_pthread_barrier instead of
struct sparc_pthread_barrier. Pass
ibarrier->s.pshared ? LLL_SHARED : LLL_PRIVATE to lll_{,un}lock
and lll_futex_wait macros.
* sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/pthread_barrier_init.c:
Remove.
* sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/pthread_barrier_wait.c:
Include sparc pthread_barrier_wait.c instead of generic one.
