PR port-vax/50384: NetBSD/vax 7.0 gcc-4.8.4 gets ICE by SIGILL

Fix for https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=50384
as encountered in gcc 7 in NetBSD 7.

VAX's FFS instruction as used in GCC's count_zero and ffssi2 instructions
uses the Z flag to indicate whether a set bit was found or not; GCC expects
the Z flag to consistently indicate whether the result is zero.
