Versions 11 and 12 (predating gcc-for-host) include a lot of
cross-architecture undeclared file conflicts. Doing archive wide
conflict analysis is dominated by these two packages and poses a
significant additional cost on that work.

Yes, just keeping them poses a cost. Now it s up to you and me how to
deal with that. I see three possible routes forward:

 * Delete them from the archive
 * Fix the undeclared file conflicts
 * Exclude them from conflict analysis

I hope you can see how I find the first option most attractive, but then
I'm probably missing parts of the bigger picture.
