Neat, I only took a quick look; I guess I misinterpreted their purposes.

When I tried, early in the WSL testing, bitbake wouldn't start due to
some missing syscalls. inotify related, IIRC.

The problem I'm running into right now is pseudo. FreeBSD uses a
different API for extended attributes, so all the various xattr_...
things don't work. I might need to make it depend on a port of the
xattr wrappers.

Outside of that, I've been using a FreeBSD hosted cross toolchain for
embedded Linux for years. It works well on its own. Hopefully the
build-* overrides will be helpful for the small differences I've
noticed.
