-Subject: Revert "Use more binaries from clang toolchain in mac build"
-
-This reverts commit 17b850a9f8e913fb5e465d895f545b069def57d1.
-
-As part of the above commit, Chrome began bundling their otool
-and nm binaries into third-party/llvm-build. These binaries are
-not found in our current CI builds, and we'll need to modify
-our actions to ensure they either persist or are added on MacOS.
-
-This patch can be removed when both otool and nm are correctly
-persisted with third-party/llvm-build.
