This is the full build directory.

to reach the error in there do:
$ postgresql-12-12.2/build/tmp_install/usr/lib/postgresql/12/lib/bitcode
$ /usr/lib/llvm-10/bin/llvm-lto -thinlto -thinlto-action=thinlink -o postgres.index.bc postgres/access/brin/brin.bc

I extracted the same on x86 and tried it there, it works on x86.
So you really will need an s390x system to trigger the crash.
