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.

r c C s" 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).
