    69           <para>Because this is really a native build of Binutils, setting these
    70           variables ensures that the build system uses the cross-compiler and
    71           associated tools instead of the ones on the host system.</para>

    77         <listitem>
    78           <para>This tells the configure script to specify the library
    79           search path during the compilation of Binutils, resulting in
    80           <filename class="directory">/tools/lib</filename> being passed
    81           to the linker. This prevents the linker from searching through
    82           library directories on the host.</para>

    87         <term><parameter>--with-sysroot</parameter></term>
    88         <listitem>
    89           <para>This defines a default (non-existent) sysroot directory
    90           <filename class="directory">/tools/$LFS_TGT/sys-root</filename>.
    91           It is useful when looking for shared objects which are required by
    92           other shared objects explicitly included on the linker's command
    93           line. Those objects are searched into the directories listed in
    94           <filename>&lt;sysroot&gt;/etc/ld.so.conf</filename>, and failing
    95           that, into the linker search path, which is right. If this switch
    96           is not given, <filename>/etc/ld.so.conf</filename> on the host
    97           is used, that is, programs may be linked to libraries on
    98           the host, which we want to avoid.</para>
     67          <para>This tells the configure script that we want to build
     68          this pass of binutils for the $LFS_TGT machine, using our just
     69          built cross-compiler.  This prevents the linker from searching
     70          through library directories on the host.</para>

    137           allows us to override the default value of the temporary tools
    138           and point it to the proper final path. The value of this variable
    139           specifies the linker's default library search path. This
