Just to save some time, for whoever is triaging the currently failing master-
next build, I added a change to bitbake which shows errors for questionable git
url usage. This appears to:
* show errors in meta-aws which I reported to them
* fails in world builds (including source fetching) - I need to fix that
* fails in one of the oe-selftests - that looks like a bug in recipetool not
setting PV correctly
The buildtools issue is known about and waiting for a new uninative release.
