Even though this behavior is now the default, I strongly recommend that
you keep the option documented, but with wording stating that the option
now does nothing, and exists solely for compatibility with Makefile.am
written to be portable across a range of automake versions.  Completely
undocumenting it will cause more problems than it solves.
