Yes, this is wrong since oldglob.c as default will create symbol where
for s390 it should not.  S390 requires a arch-specific oldglob.c as

#define GLOB_NO_OLD_VERSION
#include <sysdeps/unix/sysv/linux/oldglob.c>

So glob64.os will the only object providing glob64 symbols.  With this
file now I see:

$ /s390x-glibc-linux-gnu-objdump -t posix/glob64.os | grep glob64
posix/glob64.os:     file format elf32-s390
000009b0 g     F .text  0000144e __glob64
000009b0 g     F .text  0000144e .hidden __GI_glob64
000009b0 g     F .text  0000144e glob64
$ s390x-glibc-linux-gnu-objdump -t posix/oldglob.os | grep glob64
$ 

I will fix it and maybe it is confusing the linker and making you seem
the missing glob64 (since oldglob.os and glob64.os both provide the
same symbol).
