Make -Wl,--undefined-version google-only.

tensorflower-gardener · tensorflower-gardener · commit df4713056a31 · 2023-05-08T21:40:27.000-07:00
--undefined-version was added to work around tensorflow_jni linking with newer ld.lld that defaults to --no-undefined-version.

```
ld: error: version script assignment of 'VERS_1.0' to symbol 'JNI_OnLoad' failed: symbol not defined
ld: error: version script assignment of 'VERS_1.0' to symbol 'JNI_OnUnload' failed: symbol not defined
```

However, --undefined-version is unsupported by GNU ld&lt;2.40. Don't add it for now.
