    This function will strip '-isysroot PATH' and '-arch ARCH' from the
    compile flags if the user has specified one them in extra_compile_flags.

    This is needed because '-arch ARCH' adds another architecture to the
    build, without a way to remove an architecture. Furthermore GCC will
    barf if multiple '-isysroot' arguments are present.

cCs"t�st|�t|�t|�|S)a�Customize Python build configuration variables.

    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).

    Currently called from distutils.sysconfig
