Setup target-specific variables for the compiler and linkers:
export CC="${CLFS_TARGET}-gcc ${BUILD64}"
export CXX="${CLFS_TARGET}-g++ ${BUILD64}"
export AR="${CLFS_TARGET}-ar"
export AS="${CLFS_TARGET}-as"
export RANLIB="${CLFS_TARGET}-ranlib"
export LD="${CLFS_TARGET}-ld"
export STRIP="${CLFS_TARGET}-strip"
      The meaning of the new configure options:
CXX="${CXX}
            ${BUILD64}"
          This forces the C++ compiler to use our 64 Bit flags.
        Then add the build variables to ~/.bashrc to prevent issues if you stop and come
        back later:
      
echo export CC=\""${CC}\"" >> ~/.bashrc
echo export CXX=\""${CXX}\"" >> ~/.bashrc
echo export AR=\""${AR}\"" >> ~/.bashrc
echo export AS=\""${AS}\"" >> ~/.bashrc
echo export RANLIB=\""${RANLIB}\"" >> ~/.bashrc
echo export LD=\""${LD}\"" >> ~/.bashrc
echo export STRIP=\""${STRIP}\"" >> ~/.bashrc
