For cross-build-dependencies, Architecture: all packages should be

treated as implicitly Multi-Arch: foreign, because either they *are*
M-A: foreign when used as a build-dependency, or they need to be updated
to not be Architecture: all; and since cross-build-deps are new
functionality in apt, we can safely make this change without breaking
existing systems.  Closes: #666772.
