    net/norm: fix build with clang 16

    Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
    Because net/norm's build system does not explicitly set the C++
    standard, this leads to several errors:

      ../src/common/normEncoderRS8.cpp:264:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
          USE_GF_MULC ;
          ^
      ../src/common/normEncoderRS8.cpp:136:21: note: expanded from macro
'USE_GF_MULC'
      #define USE_GF_MULC register gf * __gf_mulc_
                          ^
      ../src/common/normEncoderRS8.cpp:265:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
          register gf* dst = dst1;
          ^~~~~~~~~
      ../src/common/normEncoderRS8.cpp:266:5: error: ISO C++17 does not allow
'register' storage class specifier [-Wregister]
          register gf* src = src1 ;
          ^~~~~~~~~

    Add USE_CXXSTD=gnu++98 to compile for C++98 with GNU extensions instead,
    as net/norm does not seem to use any C++11 or later constructs.
