I think the error above comes from a "mismatch" between the clang used
to compile bitcode, and the LLVM version linked to. Normally we're
somewhat tolerant of differences between the two, but there was an ABI
change at some point, leading to that error. IIRC I hit that, but it
vanished as soon as I used a matching libllvm and clang.
Thanks, I passed that advice on.

Tom Stellard was so kind to look at this issue deeper with his LLVM
skills and found PostgreSQL is not actually handling the LLVM
perfectly. He's working on improving the patch, but sharing even the
first attempt with upstream seems like a good idea:
https://src.fedoraproject.org/rpms/postgresql/pull-request/29
I wrote a new patch based on the bug discussion[1]. It works around
the issue specifically on s390x rather than disabling specific
CPUs and features for all targets. The patch is attached.

Thanks, Tom, it looks good in koji build, so merging so far. We very
much appreciate your help here.
