  # - Remote executions or when doing official builds.
  # - When using cc_wrapper because ccache requires a particular configuration
  #   and some compiler options currently not used by Chromium:
  #   https://ccache.dev/manual/latest.html#_precompiled_headers and it isn't
  #   supported by sccache: https://github.com/mozilla/sccache/issues/978.
  # - On Linux it slows down the build.
