[llvm-dev] libfuzzer tests on Linux

I was obviously looking at the wrong CI, the proper URL is http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer/builds/6489/steps/stage2%2Fasan%2Bassertions%20check-fuzzer/logs/stdio

However, for me tests are still failing, *unless* I explicitly build "llvm-symbolizer” before running “ninja check-fuzzer”.
I strongly suspect that the CI machine just has llvm-symbolizer already installed in $PATH, and that’s why the tests succeed.
