To be fully multi-arch compliant, you should in theory use
"${binary:Package}" instead of ${Package}. That way multi-arch: same
package will be arch-qualified.

But for backwards compatibility, you'll have to detect when
it's available. (And just testing "dpkg --assert-multiarch" will
break on Ubuntu since the current multiarch implementation there
doesn't know this field under this name)

The easiest is to put both fields in the query and to use the one
that's not empty.
