Looking at #670322, I think it has to be handled at the libapt level,
because apt does not seem to know that libc6:armel even exists, and so
neither does aptitude.

BTW, this particular problem is fixed in unstable's apt, so if you want
to continue using multiarch, please upgrade.

This is still reproducible in unstable, and apt-get behaves exactly the
same way, so I'm reassigning this bug to apt.
