Yes, that's right.

Unfortunately, it only supports cross-architecture compilation -- not
cross-OS compilation.  So you can use it to build packages for
NetBSD/earmv7hf using, say, NetBSD/amd64, but not using macOS.

Fortunately, I am sitting on some changes to extend this to cross-OS
compilation, so soon it will be possible.  But I'm busy working on
getting netbsd-10 out the door, so it won't be until after 2023Q3 is
out that I'll get back to pkgsrc cross-compilation.
