    Makes the CI work again with ClangAnalyzer v6.x
    
    There are a few issues with clang and how we do things:
    
          1) The autoconf module we use for C++ version detection
          puts the -std=c++17 in the CXX variable, but not CXXFLAGS.
          This fails when you wrap the compilers like we do with scan.
    
          2) The STL includes on CentOS7 are much too old, and clang
          seems to prefer those over its own for some odd reason. So,
          enforce the use of the LLVM/clang include files.
    
          3) We must also link with an appropriate C++ standard library.
          Similar to 2), we therefore specifically use libc++.
