s3: handle non-POSIX compliant Tru64, NetBSD and FreeBSD errno on O_NOFOLLOW symlink open calls
or should we leave the NetBSD and FreeBSD platforms just broken? Actually these
two *want* to have broken platforms as they use different errno's than POSIX
demands *interntionally*. The POSIX errno ELOOP for O_NOFOLLOW open calls on
symlinks is clear and unambiguous. See http://gnats.netbsd.org/43154 for the
interesting NetBSD discussion on that.
