Starting with commits -7ea510127e
string: Add libc_hidden_proto for strchrnul -22999b2f0f
string: Add libc_hidden_proto for memrchr building glibc on s390x with --disable-multi-arch fails if only the C-variant of strchrnul / memrchr is used. This is the case if gcc uses -march < z13. The build fails with: ../sysdeps/s390/strchrnul-c.c:28:49: error: ‘__strchrnul_c’ undeclared here (not in a function); did you mean ‘__strchrnul’? 28 | __hidden_ver1 (__strchrnul_c, __GI___strchrnul, __strchrnul_c); With --disable-multi-arch, __strchrnul_c is not available as string/strchrnul.c is just included without defining STRCHRNUL and thus we also don't have to create the internal hidden symbol.
