bpo-26317: Support OBJC and OBJCXX configure command line variables (GH-20176)
Add support to the configure script for OBJC and OBJCXX command line options so that the macOS builds can use the clang compiler for the macOS-specific Objective C source files. This allows third-party compilers, like GNU gcc, to be used to build the rest of the project since some of the Objective C system header files are not compilable by GNU gcc.

* The ``OBJC`` and ``OBJCXX`` standard command line options for the configure
|

script are now supported. This allows building fot macOS with a third-party
|
||||
compiler, like GNU `gcc`, for everything except for the several

system-specific source files that need system headers that require the

Apple-supplied compile chain (e.g. the ``_scproxy`` helper module and

``PythonLauncher.app``).
