config.guess - guess the build system triplet
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.
Output the configuration name of the system `config.guess' is run on.

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
specify `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host'
CC_FOR_BUILD a native C compiler, defaults to `cc'
CC a native C compiler, the previous variable is preferred
