ifconfig-i386 on 8-STABLE/amd64

Hi,

I've got a 32-bit build on a 8-STABLE/amd64 machine, built using
instructions at:

http://wiki.freebsd.org/Wine#head-6963d527c173e57b1567e881305b544d33435b6d

And I'm noticing some odd output from ifconfig (commands are run from
the non-chrooted env):

    $ /sbin/ifconfig
    xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu

        inet 127.0.0.1 netmask 0xff000000 
    ifconfig: ioctl(SIOCGIFINFO_IN6): Device not configured

Why is the output from the 32-bit ifconfig severely mangled?

Cheers.

My understanding is that 32-bit management tools like ifconfig is not
supported on 64-bit FreeBSD.  Someone has to sit down and write a
compatibility layer for translating back and forth :(
