Thank you. You are correct. The patch cannot work as is. The patch can
only change the Multi-Arch field of tool packages, not for library
packages. Library packages should be Multi-Arch: same. However, we are
converting those architecture-dependent Multi-Arch: same packages to
libsomething-somearch-cross packages using dpkg-cross. And then they
become Multi-Arch: foreign. Since they, too, carry the architecture in
their name, they should be Multi-Arch: foreign as well. That's a pretty
simple change to dpkg-cross. So we need both patches in combination
here.
Could you try answering the other question from my mail about why the
Multi-Arch field would be harmful?
