I think it's probably best not to do this, at least just yet.  As far as
I can see this is not yet in any released version of Autoconf.  The NEWS
file in git says:

- AC_CONFIG_MACRO_DIRS
  New macro, used to declare multiple directories when looking for
  local M4 macros.  This macro overcomes some of the shortfalls in the
  older AC_CONFIG_MACRO_DIR, which could only be used once; although
  the older macro remains for compatibility with older tools.  The
  newer macro will be used by the upcoming Automake 1.13 release to
  eliminate the need to specify ACLOCAL_AMFLAGS in Makefile.am.

For the time being, we already specify ACLOCAL_AMFLAGS in
man-db/Makefile.am, so if the worst it causes is a warning on some
systems then I'm inclined to leave it there until this new macro is *at
least* in a released version.

I suspect that you only see a warning because you're using a post-2.69
snapshot of Autoconf.

Thanks,
