Which is done for you by the dependency system on Ubuntu and Debian using multiarch. https://wiki.debian.org/Multiarch/HOWTO And Ubuntu Saucy now has lots of arm64 packages you can use: http://ports.ubuntu.com/dists/saucy/main/binary-arm64/ So you should be able to debootstrap an arm64 image and add armhf binaries to it, or vice versa. I've not actually tried that so I don't know how well it works. There may still be important bits missing.
