Fix a rather nasty problem with signals, namely SIGCHLD, that prevented
running threaded binaries if SIGCHLD was set to SIG_IGN. What happens is
that pthreads uses either sigaction() or signal() to set up signals when
switching thread state. It used HAVE_SYSCALL_SIGACTION to decide which to
use. But, while we have a FUNCTION called sigaction(), the syscall is
__sigaction14, which caused HAVE_SYSCALL_SIGACTION to not be defined.
This would have been ok if the pthread kernel didn't assume signal would
return 0 for success and non-zero for failure. Signal() returns the
previous handler. SIG_IGN != 0, so pthreads thought the call failed.
Resulting in a call to abort().
