Unless you have very specific test cases, I doubt that something's
"wrong" with the CPU emulation, it'll just be emulating an older CPU
than your code was compiled for. Userspace emulation may be more
complete, you could try running `qemu-s390x someelflinuxexecutable`
rather than `qemu-system-s390x -kernel ...` to verify that.
