Work around a problem on macppc with kernel semaphores.
NetBSD/macppc 7 and later seems to have a bug in kernel based pthread
semaphores. When running emu interactively shell would forever hang
in sem_wait() after the first interactive command.
I added sem_getvalue() after sem_init() as a debugging aid to get the
semaphore id in ktrace output and it magically fixed the problem. For
now just leave it here as a workaround under appropriate ifdef.
