What to change

Update the buildtools dependency to:

mercurial	git
168dac24ad9e	f679caf

According to #6625, include resolve.alias and it's documentation in the repositories README.md.

Hints for testers

The builds should not have changed at all.

As long as these are the only new changes in buildtools, I'm fine with performing the dependency update implicitly as part of #6621. Before #6621 lands, this dependency update won't have any effect on the builds anyway, and that way we can also validate that the changed done for #6625 are sufficient.

FWIW, geo failed so far to use the module switching mechanism introduced in #6625. Perhaps you can show her a working example similar to what we want to do in #6621.

Geo and i got it running yesterday, so from my point of view we're all good.

I wouldn't mind the implicit update with #6621 either - what do you think, Geo?

In case we all agree here, i'll close this ticket. (@Geo, feel free to contact me again if you need any support)

I think the implicit update with #6621 is fine as long as it doesn't block any other issues.

The update will be done in #6621.
