thanks a lot for your guidance on this. However libbsd is broken on i386
due to missing fixes/files. See #4052 and #4053 for more information.

I've had a curious look into what's going on there trying to cherry-pick
fix from the 5-freebsd-12 branch, but the problem is currently over my
available time and knowledge. If it's not fixed, I'll hopefully get back
to it and try to work on it properly in upcoming weekends.
