-    <para os="e">Here we will compile GCC, as a cross-compiler that will create
-    executables for our target architechture, statically so that it will not
-    need to look for Glibc's startfiles, which do not yet exist in
-    <filename class="directory">/tools</filename>. We will use this
-    cross-compiler, plus the cross-linker we have just installed with Binutils,
-    to compile Glibc. After Glibc is installed into
-    <filename class="directory">/tools</filename>, we can rebuild GCC
-    so that it will then be able to build executables that link against the
-    libraries in <filename class="directory">/tools</filename>.</para>
