I was cross-compiling for s390x.

Just to clarify, you mean Linux on IBM Z/LinuxOne, not 64bit ZOS/ZVM,
right?

I'm sorry, I'm not aware of the correct terminology here.

If I run file(1) on the compiled binary, I'm getting:

    ELF 64-bit MSB pie executable, IBM S/390, version 1 (SYSV),
    dynamically linked, interpreter /lib/ld64.so.1, for GNU/Linux 3.2.0

And readelf(1) says:

    ...
    OS/ABI:                            UNIX - System V
    ...
    Machine:                           IBM S/390
    ...

And the toolchain used was installed from:

    https://aur.archlinux.org/packages/s390x-z13-glibc-bleeding-edge-toolchain

I hope that clarifies it?
