Bug#827718: init: open /dev/console on GNU/kFreeBSD

Package: busybox
Version: 1.22.0-19
Tags: patch

FreeBSD kernel doesn't tell PID 1 the pathname of /dev/console through CONSOLE environment variable like Linux does. Instead it expects PID 1 to always open /dev/console.

This patch is tested on ubuntuBSD but I think it should work on Debian too (I haven't tested the whole init yet, but I verified that with my patch it can print to stdout).

I've also sent it to BusyBox bugzilla: https://bugs.busybox.net/show_bug.cgi?id=9031
