You'd better document extensively such inconsistencies such that, when
they're addressed, we can re-enable the cache, without the risk of
urban legends about problems long solved holding it back.

Anyway, naming a config.cache file for the host is wrong.  The user is
entitled to name a config.cache they want configure to use, and it
should be honored at the very least for host packages.
