Comment (by simonpj):
Simon and I looked briefly at this:
* The `mg_foreign` field of a `ModGuts` records the foreign-stub
information
* It would be straightforward to add a `Bool` to `ModIface` to record
whether there were stubs
* The only tricky bit is making use of that `ModIface` field to construct
the right `hm_linkable` list of `Linkables`, recorded in `HomeModInfo`.
So this is probably not hard to fix; just a bit fiddly to poke around and
see what needs to be done. Any volunteers?
