Called internally from sysconfig with a mutable mapping containing name/value pairs parsed from the configured makefile used to build this interpreter. Returns the mapping updated as needed to reflect the environment in which the interpreter is running; in the case of a Python from a binary installer, the installed environment may be very different from the build environment, i.e. different OS levels, different built tools, different available CPU architectures. This customization is performed whenever distutils.sysconfig.get_config_vars() is first called. It may be used in environments where no compilers are present, i.e. when installing pure Python dists. Customization of compiler paths and detection of unavailable archs is deferred until the first extension module build is requested (in distutils.sysconfig.customize_compiler).
