-config.guess might need to compile and run C code, hence it needs a
-compiler for the `build' machine: use the environment variable
-`CC_FOR_BUILD' to specify the compiler for the build machine. If
-`CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to

-[description]
-The GNU build system distinguishes three types of machines, the
-`build' machine on which the compilers are run, the `host' machine
-on which the package being built will run, and, exclusively when you
-build a compiler, assembler etc., the `target' machine, for which the
-compiler being built will produce code.

-This script will guess the type of the `build' machine.
