No, it doesn't matter whether you have a foreign arch enabled or not.
Multi-Arch: same packages are always qualified with their architecture
in dpkg's output (starting with dpkg 1.16.2).

However it will only refuse the unqualified name when you have 2 arches
installed for a given package (i.e. "dpkg -s libc6" will work if you have
only libc6:386 but it will break if you have libc6:i386 and libc6:amd64).

$ dpkg-query -W libc6:*
libc6:amd64 2.13-27
libc6:i386  2.13-27

But in most cases, I believe it's best to not ask the user and
automatically try with "package:<native-arch>" by default. Or maybe
only ask in expert mode... you can emit a warning saying that
other arches were installed and that the user could have given an
arch qualifier to remove the ambiguity.
