The full build log is available here [1].
The issue is due to the definition of ONCE_FLAG_INIT 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
