fix stack overflow detection to handle sigbus

2008-01-17  Doug Young  <[email protected]>

        * kaffe/kaffevm/systems/unix-pthreads/signal.c (stackOverflowDetector),
        kaffe/kaffevm/systems/unix-jthreads/signal.c (stackOverflowDetector):
        The sig argument should be used to clear the signal, since it could
        be either SIGSEGV or SIGBUS.
