I just applied this to a recent HEAD and got a few warnings. Please make sure
there are no new warnings on changes / new files.

etc.
There is also a test error:

I'm guessing this is the path of a local sysroot you have on your machine?
If possible, try to get a new environment (container, VM, alternative machine)
and make sure a clean build still passes the tests.
