 Getting the Canonical System Type
 =================================
 
    The following macros make the system type available to `configure'
 scripts.  They run the shell script `config.guess' to determine any
 values for the host, target, and build types that they need and the user
 did not specify on the command line.  They run `config.sub' to
 canonicalize any aliases the user gave.  If you use these macros, you
 must distribute those two shell scripts along with your source code.
  Output, for information about the `AC_CONFIG_AUX_DIR' macro
 which you can use to control which directory `configure' looks for
 those scripts in.  If you do not use either of these macros,
 `configure' ignores any `--host', `--target', and `--build' options
 given to it.
 
  - Macro: AC_CANONICAL_SYSTEM
      Determine the system type and set output variables to the names of
      the canonical system types.   System Type Variables, for
      details about the variables this macro sets.
 
  - Macro: AC_CANONICAL_HOST
      Perform only the subset of `AC_CANONICAL_SYSTEM' relevant to the
      host type.  This is all that is needed for programs that are not
      part of a compiler toolchain.
 
  - Macro: AC_VALIDATE_CACHED_SYSTEM_TUPLE (CMD)
      If the cache file is inconsistent with the current host, target
      and build system types, execute CMD or print a default error
      message.
