What "does not work" exactly ?

Yes, you end up with host-rust being built as a dependency of
host-cargo, while BR2_PACKAGE_HOST_RUST is not enabled.

But for host packages, we currently don't enforce that their
Config.in.host option is enabled when the package is built.

So, which problem have you encountered ?

I agree that your patch makes sense (it's better to have the
Config.in.host option enabled when the corresponding host package is
going to be built), but I don't see where the *problem* is, so I'd like
to understand before applying.

Thanks!

Thomas
