I did originally say that I thought the qemu package should pull in all
of the sub packages to maintain compatibility. I'm not sure having it
pick the host architecture like this is a great idea and certainly it
changes the default behaviour again.

I'd much rather than picked a design then implementing it than keeping
changing behaviour like this :(.

I'm not seeing many other opinions though.

Cheers,

Richard
