%%% src_config
The code below from original LFS is not used:

\begin{verbatim}
  case $(uname -m) in
    x86_64) mkdir -v /tools/lib && ln -sv lib /tools/lib64 ;;
  esac
\end{verbatim}

We do not create files or links in filesystem directly.
To merge \Arg{lib} and \Arg{lib64} directories, special code is used after build of each package.
It is located in \File{lfs/lib/lfs.sh} in function \Arg{lfs_install_pass1}.

Option \Opt{--with-sysroot} is used without argument, replacing original
\Opt{--with-sysroot=}\Arg{$LFS}.
