some of these functions were returning. That makes the +1word address
a fairly strong and easily located gadget. Put a hard-trap
instruction after the syscall. This remains a gadget for 'terminal
system' calls (such as execve), but hey that's why we have pledge w/o
"exec" throughout the tree.
Quite surprisingly, hppa's delay-slot load of SYS_exit makes it the
safest of the bunch, not that this helps anyone.
