I'm about to update my feature branch again and from now on, to build it
with poudriere, a patch will be needed.

Here's a quick and dirty patch against an *installed* poudriere-devel:
https://people.freebsd.org/~zirias/patches/poudriere-devel-linuxulator-build.patch

I guess my next priority should be to look into getting this (or maybe a
better, less "hacky" approach) into official poudriere...

Background is, right now, poudriere does not provide /compat/linux/dev
inside a building jail, but build systems at least need /dev/null quite
a lot. I'm about to add a port for "man-db", which will only build fine
using "bash" and "make" from inside linuxulator userland, so it needs
/dev available there.

Cheers, Felix
