nptl: Remove sparc sem_wait
This patch removes the sparc32 sem_wait.c implementation since it is identical to default nptl one. The sparcv9 is no longer required with the removal. Checked with a sparcv9 build. * sysdeps/sparc/sparc32/sem_wait.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_wait.c: Likewise.
