In a clang-17[default-libcxx] environment, media-libs/libva-2.19.0 will fail to link during emerge with the following error message:

```

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
```

This can be avoided by passing "-Wl,--undefined-version" to LDFLAGS.

Just released libva-2.20.0 will possibly fail the same.

Reproducible with media-libs/libva-2.20.0
