Comment (by jmroot):

 Yeah, it looks like setting `github.tarball_from` sets master_sites. So if
 you do that before git.branch has its final value, it will be incorrect.

 No need for a rev bump when fixing this BTW, since it has never been able
 to build, and the mirror job will notice that the checksum doesn't match
 and re-download.
