    math/cbc: fix build with clang 16
    
    Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
    Because math/cbc's build infrastructure does not explicitly set its C++
    standard, this leads to errors:
    
      ./CbcSymmetry.hpp:83:30: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
          inline void color_vertex(register int k) { color = k; }
                                   ^~~~~~~~~
      ./CbcSymmetry.hpp:91:24: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
          inline void bounds(register double a, register double b)
                             ^~~~~~~~~
    
    To work around the error, add USE_CXXSTD=gnu++11 to compile for C++11
    with GNU extensions instead.
