--- Comment #2 from Stefan Liebler <stli at linux dot ibm.com> ---
I've also tried with 2.38 release branch
(cfe121910013a46e2477562282c56ae8062089aa) with gcc 13
(5d0d592c486c31bd9c26af0d1f0a7b6a3d68c22b) and I don't get a build fail.

If you manually run the gcc-compile-command producing strchrnul-c.os in
<glibc-src>/string/ with -save-temps, the strchrnul-c.i file should have
included <glibc-src>/string/strchrnul.c with __strchrnul_c instead of
__strchrnul.

Then the internal symbol __GI___strchrnul should be __strchrnul_c (See your
error-message from <glibc-src>/sysdeps/s390/strchrnul-c.c).
The weak_alias should be the IFUNC __strchrnul (See
<glibc-src>/sysdeps/s390/strchrnul.c)
