+<title>Re-adjusting the toolchain</title>
+<?dbhtml filename="adjustingtoolchain.html" dir="chapter05"?>
+
+<para>Now that we have compiled all the necessary tools, it is time to
+re-adjust our toolchain. We will set it up so that it will link any newly
+compiled program against the new Glibc, which is the first thing to get
+compiled in the next chapter. Basically, this is the reverse of what we did
+in the "Locking in" stage in the beginning of this chapter.</para>
+
+<para>The first thing to do is to adjust the linker scripts. For this we
+retained the <filename>binutils-build</filename> directory from the second
+pass over Binutils. Do the following:</para>
+
+<para><screen><userinput>cd binutils-build
+make -C ld INSTALL=/stage1/bin/install install-data-local</userinput></screen></para>
+
+<para>This installs the adjusted linker scripts. The linker scripts now contain
+no mention of <filename>/stage1/lib</filename>. From now on every compiled
+program will link <emphasis>only</emphasis> against the libraries in
+<filename>/usr/lib</filename> and <filename>/lib</filename>. The extra
+<userinput>INSTALL=/stage1/bin/install</userinput> is needed because the
+Makefile created during the second pass still contains the reference to
+<filename>/usr/bin/install</filename>, which we obviously haven't installed
+yet.</para>
+
+<para>You can now remove the Binutils source and build directories.</para>
+
+<para>The next thing to do is to amend our GCC specs file so that it points to
+the new dynamic linker. Just like earlier on, we use a sed to accomplish
+this:</para>
+
+<para><screen><userinput>CURRENTSPECFILE=/stage1/lib/gcc-lib/*/*/specs
+sed -e 's@/stage1/lib/ld.so.1@/lib/ld.so.1@g' \
+&nbsp;&nbsp;&nbsp;&nbsp;-e 's@/stage1/lib/ld-linux.so.2@/lib/ld-linux.so.2@g' \
+&nbsp;&nbsp;&nbsp;&nbsp;$CURRENTSPECFILE > newspecfile
+mv newspecfile $CURRENTSPECFILE
+unset CURRENTSPECFILE</userinput></screen></para>
+
+<para>Again, cutting and pasting the above is recommended. And just like
+before, it is a good idea to check the linker scripts and the specs file to
+ensure the intended changes were actually made.</para>
+
+<para>Note that the linker scripts will still contain a reference to
+<filename>/stage1/i686-pc-linux-gnu/lib</filename>. This is unavoidable, but
+luckily does not present a problem. There are no libraries in that location
+as all the temporary stage1 libraries are located in
+<filename>/stage1/lib</filename>.</para>
