Hi,

This addresses all of the Go compilation issues on the
head except one.

Ian.. Is this OK to commit? Or do you have suggestions
on how to make it more general?

Thanks.

         * runtime/go-signal.c: Add conditional on SIGPROF.
         * runtime/mem_posix_memalign.c: Add USED directives.
         * libgo/go/syscall/wait.c:  Conditionalize on WIFxxx macros
         and SIGxxx being defined.

I committed the changes to runtime/go-signal.c and
runtime/mem_posix_memalign.c.

As I mentioned in an earlier message, we probably don't want to compile
wait.c on RTEMS at all.  I will work on that now.
