--- Comment #3 from William Cohen <wcohen at redhat dot com> ---
This looks like an issue with systemtap understanding the debuginfo generated
as part of the rpmbuild process.  When locally building the
glibc-2.34-83.el9_3.7.src.rpm on the machine the following work fine on the
unstripped glibc.so.6:

[root@s390x-kvm-033 build-s390x-redhat-linux]# 
~/systemtap_write/install/bin/stap -v -L
'process("./libc.so.6").function("malloc_init_state")'
Pass 1: parsed user script and 489 library scripts using
127764virt/106232res/10972shr/94700data kb, in 230usr/30sys/256real ms.
process("/root/rpmbuild/BUILD/glibc-2.34/build-s390x-redhat-linux/libc.so").function("malloc_init_state@/root/rpmbuild/BUILD/glibc-2.34/malloc/malloc.c:1932")
/* pc=.dynamic+0xab576 */ $av:mstate
process("/root/rpmbuild/BUILD/glibc-2.34/build-s390x-redhat-linux/libc.so").function("malloc_init_state@/root/rpmbuild/BUILD/glibc-2.34/malloc/malloc.c:1932")
/* pc=.dynamic+0xab9e0 */ $av:mstate
Pass 2: analyzed script: 2 probes, 0 functions, 0 embeds, 0 globals using
137564virt/117272res/12220shr/104500data kb, in 50usr/0sys/57real ms.

However, install the rpms created from that same build a wildcard is needed to
find malloc_init_state:

#cd rpmbuild/RPMS/s390x/
#dnf install -y ./glibc-gconv-extra-2.34-83.el9.7.s390x.rpm
