The full build log is available here [1].
The issue is due to ISO C23 declaration of bsearch, memchr, strchr,
strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr,
which now returns a pointer to a const-qualified type when the input
argument is a pointer to a const-qualified type [2].
I would like to thanks Emanuele Rocca for doing the archive rebuild on
a fast arm64 server.
Regards
Aurelien
