FYI: This is a non-issue for apt-ma-emu. The libfoo-dev-arch-cross
package will just depend on libfoo-dev-common or
libfoo-whatever-arch-cross and pull them in too. This then becomes a
dpkg-cross issue to do the right thing with the package (which I think
it will anyway).
So maybe we can ignore this issue till the experimental apt moves into
sid and apt-ma-emu can replace apt-cross?

Similar in apt-ma-emu, which looks at the architecture when it decides
wether to rename a package or not in addition to its pattern list.
