commit 8e6db769ac549cfe26042f7d51ae8a301d8fc569
from: Federico G. Schwindt <fgsch@lodoss.net>
date: Wed Oct 23 15:00:26 2013 UTC

Check and call arc4random_stir() if present

FreeBSD prior to 10.0 does not automatically stir on fork(). Same with
current NetBSD. If arc4random_stir() is present assume is needed and
call it instead of srand().
