Lantiq gone from Bitbucket, onsub repository dead
Created originally on Bitbucket by gstefanik (Gábor Stefanik)
Lantiq has merged with Intel, and its Bitbucket presence has been deleted. This renders builds impossible due to onsub being unavailable.
Bitbucket now considers https://bitbucket.org/nikolausschueler/onsub to be the authoritative fork, but this one is unmaintained, with an outstanding pull request for Hg 3.8+ support. The best maintained fork appears to be https://bitbucket.org/kvaster/onsub.
