 > Yes, GCC is built exactly in the same way in both cases, the only
 difference is the list of packages installed in the containers, and the
 `dpkg --add-architecture i386` we only run in the i686 case (which are
 causing the hash in the filename to differ).

 That means we need to have two containers for that. Then I think we just
 can fold the i686 stuff that does make a difference into the x86_64 parts,
 so that we can avoid having two containers and two GCCs.
