    multimedia/smpeg: fix build with clang 16
    
    Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
    Because multimedia/smpeg's configure scripts and Makefiles do not
    explicitly set the C++ standard, this leads to several errors:
    
      In file included from MPEGaudio.cpp:24:
      ../MPEGaudio.h:129:7: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
            register int r=(buffer[bitindex>>3]>>(7-(bitindex&7)))&1;
            ^~~~~~~~~
      ../MPEGaudio.h:135:7: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
            register unsigned short a;
            ^~~~~~~~~
      MPEGaudio.cpp:317:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
        register int r=(_buffer[bitindex>>3]>>(7-(bitindex&7)))&1;
        ^~~~~~~~~
      MPEGaudio.cpp:326:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
        register unsigned short a;
        ^~~~~~~~~
      MPEGaudio.cpp:339:3: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
        register unsigned short a;
        ^~~~~~~~~
    
    Because smpeg uses a rather strange configure script, it does not
    process CXXFLAGS correctly, so set CXX to include -std=gnu++98.
    
    Also remove the REAL_CC patch which is no longer necessary.
