It is the indended solution. If it doesn't work then that is a bug and
needs to be fixed.

A Depends like in this case is never right since it mixes biarch
(libc6-i386) packages with multiarch (libfoo:i386).

I would say that a foreign dependency on a library is never right. If
the source compiles binaries for the foreign arch then the package
should be build on the foreign arch directly. Period.

Also, iirc, the use of foreign dependencies is only supposed to be on
packages with Multi-Arch: allowed. This is for interpreters and
plugins/lib bindings where the normal automatic method can't work. So
maybe DAK could be made more restrictive here.
