Cross-building ports is done with poudriere and qemu. There is some
info on setting it up in https://wiki.freebsd.org/QemuUserModeHowTo but
I think that's pretty out of date. There may be newer how-to info that
I'm not aware of. I'm going to CC the freebsd-arm@ list on this reply,
because the folks there probably know of better information resources
for all this.
I also have no idea how to integrate poudriere-based building with
release(7) stuff. It may be a matter of building a local package repo
using poudriere, then configuring the release script stuff to use it.
