How does CMAKE_SYSTEM_NAME get set to anything but Linux for a z build? 

```
if(CMAKE_SYSTEM_NAME MATCHES "Linux")
 build_generic_elf64("SystemZ" "S390X" "s390x" "s390x-ibm-linux-gnu" "22")
else()
 libomptarget_say("Not building s390x NextGen offloading plugin: machine not found in the system.")
endif()
```

That's the only way we can get this message.
