SDL_BYTEORDER - A macro that reports the target system's byte order.

       This macro is available since SDL 3.2.0.

       This is set to either SDL_LIL_ENDIAN
        or

       SDL_BIG_ENDIAN
        (and  maybe  other values in the future, if something else becomes popular). This can be tested with the
       preprocessor, so decisions can be made at compile time.

              #if SDL_BYTEORDER == SDL_BIG_ENDIAN
              SDL_Log("This system is bigendian.");
              #endif

       Defined in SDL3/SDL_endian.h
