building fuzzer failed for espeak-ng

I tried to execute

```bash
python infra/helper.py build_fuzzers --sanitizer address espeak-ng
```

but got this error:

```

Has anyone encountered this? I followed the document here https://google.github.io/oss-fuzz/advanced-topics/reproducing/

Start with infra/helper.py and projects/espeak-ng/Dockerfile, then inspect the copied build.sh. Re-run the reported build command and trace the missing libclang_rt.fuzzer_no_main-x86_64.a and tests/ssml-fuzzer.test errors; done means the espeak-ng fuzzers build successfully and the expected output is produced.
