map function is used to create hash from the contents of @b array (which contains lines from postion_file). When map is executed, its code is run for each element of the @b array. When processing those elements, they are assigned into "$_" variable inside "map" block, so (split /\s+/)[1] and (split /\s+/)[2] operate on them, extracting second and third field (position and letter) from each line. Those two elements are then returned by map into %h hash, populating it with position as the key and the letter begin its value.

About second part of your question, which built-in variables do you have in mind?

NAME
config.guess - guess the build system triplet SYNOPSIS
config.guess [OPTION] 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. Output the configuration name of the system `config.guess' is run on. Operation modes: -h, --help print this help, then exit -t, --time-stamp print date of last modification, then exit -v, --version print version number, then exit ENVIRONMENT VARIABLES
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' machine. CC_FOR_BUILD a native C compiler, defaults to `cc' CC a native C compiler, the previous variable is preferred REPORTING BUGS
