I would defer to brettw here whether there's any toolchain tricks needed here to
make sure it generates something that will run on the host architecture during
cross-compilation to generate the target dataset...

Or is this just intended to be run manually?

Yes, that's to be run manually. That's why is_ios and is_android are excluded.
