David Benjamin 6c597be1c6 Update tools. Unfortunately, this requires partially reverting https://boringssl-review.googlesource.com/31324. This is a mess. While clang proper includes a fuzzer driver, Chromium doesn't use it. Chromium builds exclusively with fuzzer-no-link and links to its own copy of the fuzzer runtime[1]. As of [2], Chromium's clang (which we use on bots) no longer includes the driver, so we must mimic them. However, Chromium's setup is somewhat questionable because fuzzer-no-link pulls in libclang_rt.fuzzer_no_main which still includes most of libclang_rt.fuzzer, just not the one main function[3]. It appears Chromium is actually linking two copies of libclang_rt.fuzzer_no_main. Hopefully this mostly works out as Chromium's clang and libFuzzer should be relatively aligned, but it's not a good assumption for our build, which can take other Clangs too. Thus, if you pass -DFUZZ=1 as-is, we will assume you are using a "normal" Clang with all its relevant runtimes intact. If, however, you are using Chromium clang, you must drop the matching libFuzzer where the bots expected it and build with -DLIBFUZZER_FROM_DEPS=1. This involves no changes to the bots because we never actually unwound all the LIBFUZZER_FROM_DEPS bits before.

This directory contains tools for setting up a hermetic toolchain on the
continuous integration bots. It is in the repository for convenience and can be
ignored in development.
