* doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.

* lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
for the existence of the directory at configure-time.  That's
too late, anyway, and possibly the directory isn't part of the
distribution.  Problem reported by Stefan Seefeld.

@defmac AC_CONFIG_MACRO_DIR (@var{dir})
@acindex{CONFIG_MACRO_DIR}
Future versions of @command{autopoint}, @command{libtoolize},
@command{aclocal} and @command{autoreconf} will use directory
@var{dir} as the location of additional local Autoconf macros. Be
sure to call this macro directly from @file{configure.ac} so that
tools that install macros for @command{aclocal} can find the
declaration before @option{--trace} can be called safely.
Specify @var{dir} as the location of additional local Autoconf macros.
This macro is intended for use by future versions of commands like
@command{autoreconf} that trace macro calls. It should be called
directly from @file{configure.ac} so that tools that install macros for
@command{aclocal} can find the macros' declarations.
