I believe we have existing occurrences of host packages being listed in
some <pkg>_DEPENDENCIES, but not necessarily selected at the Kconfig
level. While we have enforced this not to happen for target packages,
we've never enforced that for host packages.

The rationale is that host packages should normally be completely
transparent to the user, and therefore not visible in Kconfig. The host
package sub-menu is here only to make it easier for the user to enable
*some* of the host packages that are actually relevant for the user
(and not merely build dependencies of other packages).

Best regards,

Thomas
