 13.4.6 ‘config.guess’, ‘config.sub’ at top level
 ------------------------------------------------
 
    You need to add the GNU ‘config.guess’ and ‘config.sub’ files to your
 distribution.  They are needed because the ‘AM_ICONV’ macro contains
 knowledge about specific platforms and therefore needs to identify the
 platform.
 
    You can obtain the newest version of ‘config.guess’ and ‘config.sub’
 from the ‘config’ project at ‘https://savannah.gnu.org/’.  The commands
 to fetch them are
      $ wget -O config.guess 'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD'
      $ wget -O config.sub 'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD'
 Less recent versions are also contained in the GNU ‘automake’ and GNU
 ‘libtool’ packages.
 
    Normally, ‘config.guess’ and ‘config.sub’ are put at the top level of
 a distribution.  But it is also possible to put them in a subdirectory,
 altogether with other configuration support files like ‘install-sh’,
 ‘ltconfig’, ‘ltmain.sh’ or ‘missing’.  All you need to do, other than
 moving the files, is to add the following line to your ‘configure.ac’.
