    Retire WITHOUT_CXX option
    
    Several important base system components are written in C++, and the
    WITHOUT_CXX option produced a system that was not fully functional.
    Just accept this, and remove the option to build without C++ support.
    
    This reverts commit adc3c128c6603054586a993d117e5dd808deac17.
