distcc: Handle upstream branch deletion for old releases
distcc upstream dropped the 3.2 branch which we reference in older project releases
the revisions are there, just the branch is not. In order to be able to continue
to build those old releases, adjust any mirror tarball to contain the missing branch.
We have updated the newer point releases but the previous tags were failing to build.
