Use the `LIBFUZZER_WHICH_TEST`
environment variable to control which test libFuzzer runs, using a

the last test defined (which works fine if there is only one test).
Obviously, libFuzzer may work better if you provide a non-empty
corpus, but fuzzing will work even without an initial corpus, unlike AFL.
One hint when using libFuzzer is to avoid dynamically allocating
memory during a test, if that memory would not be freed on a test
