Since I was able to build in the past I was able to bisect to
r16-4315-ge63cf4b130b86d, and indeed with it reverted on top of master (and
conflicts fixed in some way) it builds again.
I'm not knowledgeable to know whether it's an issue with the script or a bug in
the tools of my debian (though I have the same issue on both my unstable and my
bookworm), but since I could bisect it seems more like a script issue.
It might also be a side effect of bug 123396 that I saw reported recently?
