nptl: Consolidate sem_init implementations
Current sparc32 sem_init and default one only differ on sem.newsem.pad
initialization. This patch removes sparc32 and sparc32v9 sem_init arch
specific implementation and set sparc32 to use nptl default one.
The default implementation sets the required sem.newsem.pad to 0 (which
is ununsed in other architectures).
I checked on i686 and a sparc32v9 build.
* nptl/sem_init.c (sem_init): Init pad value to 0.
* sysdeps/sparc/sparc32/sem_init.c: Remove file.
* sysdeps/sparc/sparc32/sparcv9/sem_init.c: Likewise.
