Spent the week working on parallelising the docker build system and adding support for armhf. I now have a script that will spin up a docker instance for each flavour of Debian/Ubuntu, download and install build dependencies, build the appropriate packages and copy them back into the host system.

I got standalone cross-compilation of armhf packages working within a single instance, but appear to have missed something when adding it to the rest of the build scripts - something is looking in the wrong paths for the dependencies. In the mean time it works fine inside the emulator, though is a little slow.
