The full build log is available here [1].
The issue is due to the definition of once_flag in stdlib.h in addition
to threads.h as part of ISO C23 [2]. I believe that the issue is fixed
upstream [3], but I haven't tested the patch.
I would like to thanks Emanuele Rocca for doing the archive rebuild on a
fast arm64 server.
Regards
Aurelien

Thanks Aurélien,
the new upstream version in Debian contains the fix you found on GitHub.
Have a nice week-end,
