Yes, of course, we want *some* host packages to be visible in
menuconfig.
Basically, the current situation is:
* Most host packages don't have any Config.in.host options (blind or
visible), because they are merely build dependencies of other
packages.
* A few host packages do have a visible Config.in.host because they
are useful by themselves, and not just as a build dependency of
something else: image generation tools, flashing tools, qemu, etc.
The idea we have for the future is:
* All host packages have a Config.in.host option.
* The host packages that are only build dependencies of other packages
have a blind Config.in.host option
* The host packages that are useful by themselves continue to have a
visible Config.in.host option.
Does that clarify where we want to go ?
