Hi Lisandro.

Thank you for replying. The bug isn't simply that there are missing
tags, but rather that you can't co-install qt5 -dev packages, thus
making cross-builds impossible. Does it not make sense to keep this open
to keep track of this feature as it is developed?

In the spirit of keeping track, are there other roadblocks to
multi-arching this? I tried to co-install the 4 packages my patch
touched, and this was the only conflicting file.

Thanks
