The current wording is quite deliberate in only allowing the use of these
directories by packages of the given architecture, because one of the ideas
to be explored in the future is introducing partial architectures for things
like w64-mingw32 (or sparc64, or armv7+neon, or amd64+sse4) that aren't
self-hosting but that it's interesting to build a subset of packages for
(mostly libraries).
So I would be opposed to making such a change in policy for the time being;
I think cross-compilers should stick with the traditional cross-compiler
directories and stay away from the multiarch directories until we have more
practical experience with multiarch under our belts and can make some
educated decisions about how we want this to all fit together.
