Emacs should be Multi-Arch: foreign

[Karl Hegbloom]

See Bug #927387

When I try to install 'mozart:i386', it fails like this:

karlheg@oaktree:~/src/Ubuntu/precise$ sudo apt-get install mozart:i386

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mozart:i386 : Depends: emacs23:i386 or
                        emacsen:i386
E: Unable to correct problems, you have held broken packages

I think that if Emacs23 was declared with Multi-Arch: foreign I would be able to install mozart. See:
