  # modification needs to be handled by the Makefile. It is possible to write
  # the Makefile where the directory is the main target for that microcode, but
  # this has worse behavior in case of modification to the directory. Worse, if
  # it was done this way, then it would break if the user tried to set
  # PARENT_OUTPUT_DIR anywhere else. So, better to support building everywhere
  # but here than to support only building here.
