  - d/juju-core.postinst.in: Bump priority of alternatives over that of
    python juju packages.
* Enable for all architectures (LP: #1172505):
  - d/control: Version BD on golang-go to >= 2:1.1.1 to ensure CGO
    support for non-x86 archs, make juju-core Arch: any.
  - d/README.source: Dropped - no longer required.
