Comment 32 for bug 1117944

Testing in Xenial...

- upgraded intltool to 0.51.0-2ubuntu1.16.04.1 from xenial-proposed
- repeated the same tarball making process for mate-desktop package,
  the only difference being the git branch (1.12 instead of master)
- the process completed successfully, the distcheck didn't break

Good to go in Xenial as well.
