That approach has a certain elegance to it...

qemu-user-static doesn't need to be multi-arch aware, you can install a 
foreign qemu-user-static just fine. I tested just now to make sure. Works like
a charm.

This adds some additional space considerations to the chroot, with the 
additional apt Package lists and the extra qemu-user-static binaries for all 
the architectures qemu-user-static supports to ship a single file.

I checked in #multiarch, and vorlon suggested no changes were needed, and then
verified for sure.
