[gnome-sdk-images/wip/tvb/aarch64: 1/7] Generate metadata & org.gnome.Sdk.json

[Tristan Van Berkom <tvb src gnome org>]

commit bbc7e77cb8bb7bc2a68622e1422f00ad0a46605a
Author: Tristan Van Berkom <tristan vanberkom codethink co uk>
Date:   Mon Apr 25 20:23:10 2016 +0100

    Generate metadata & org.gnome.Sdk.json
    
    Allows us to keep some build configurations in the same place
    so they do not have to be duplicated.
    
    Now set the architecture and versions directly in the Makefile
