Looking at this a bit closely, I see that Debian already does MOST of
this. Most qt5 packages do have multi-arch tags. This includes both
qtbase-opensource-src and qtchooser. The -dev packages do not have these
tags, however.
I'm attaching a patch that adds those tags. I looked at the contents of
the already-built packges debian ships, and it looks like the file names
are already separate, thus adding the tags is all that is necessary.
I tried to build new packages, but there's some sort of build issue
that's tripping it up:
$ DEB_BUILD_OPTIONS=parallel=7 dpkg-buildpackage -us -uc -b -j
< lots of output >
make[6]: Entering directory
`/home/dima/qtbase-opensource-src-5.2.0+dfsg/src/plugins/platforms/xcb'

Makefile.xcb-plugin xcb-plugin.pro
make[6]: /home/dima/qt5/qtbase-opensource-src-5.2.0+dfsg/bin/qmake: Command

I hit this building an unreleased git HEAD off experimental, so not
reporting this as a separate bug.

Subject: [PATCH] QT5 -dev packages are now Multi-Arch:same
This is just a change in the debian/control tag, since the package contents
already used the arch-specific paths and thus didn't conflict
