It's actually worse, since we shouldn't have qtbase5-dev multi-arch:d
either, and Debian doesn't accept it. The contents of the dev packages
differ from architecture to another, so it's a policy violation. I
haven't removed the multi-arching of it yet since it wasn't added by
me, and I'm not sure if it was required for the arm64 support added at
the same time or just something nice to have.

Currently I don't see it possible to have all of Qt (or ubuntu-sdk) to
be multi-arch:d, or at least I wouldn't know how to go forward. I also
agree we shouldn't deviate from Debian. But if there's a policy
compliant way forward it should be good enough for them too.

So in the short term (Ubuntu 13.10) I think your 'ugly but works'
solution you've started upon is needed. In the longer term it's a goal
worth having to improving the multi-arching of Qt.
