remove adjusting.xml

Now adjusting.xml only serves as a historical reference, and a "snip
library" for gcc.xml.  Put all relevant content into gcc.xml directly
and remove adjusting.xml.  If someone needs a historical reference, he
can always get adjusting.xml in Git history.

-  <title>Adjusting the Toolchain</title>
-
-  <para>Now that the final C libraries have been installed, it is time to adjust
-  the toolchain so that it will link any
-  newly compiled program against these new libraries.</para>
-
-  <para>First, backup the <filename class="directory">/tools</filename> linker,
-  and replace it with the adjusted linker we made in chapter 5. We'll also create
-  a link to its counterpart in
-  <filename class="directory">/tools/$(uname -m)-pc-linux-gnu/bin</filename>:</para>
-
-<screen><userinput>mv -v /tools/bin/{ld,ld-old}
-mv -v /tools/$(uname -m)-pc-linux-gnu/bin/{ld,ld-old}
-mv -v /tools/bin/{ld-new,ld}
-ln -sv /tools/bin/ld /tools/$(uname -m)-pc-linux-gnu/bin/ld</userinput></screen>
-
-  <para>the next command amends the GCC specs file to achieve three goals:
-  first point GCC to the new dynamic linker. Simply deleting all instances of
-  <quote>/tools</quote> should leave us with the correct path to the dynamic
-  linker. Second, let GCC know where to find the Glibc start files. Third,
-  add the /usr/include directory at the end of the default search path, so
-  that header files added in chapter 6 are found.
-  A <command>sed</command> command accomplishes this:</para>
-
-<screen><userinput>gcc -dumpspecs | sed -e 's@/tools@@g'                   \
-    -e '/\*startfile_prefix_spec:/{n;s@.*@/usr/lib/ @}' \
-    -e '/\*cpp:/{n;s@$@ -idirafter /usr/include@}' &gt;      \
-    `dirname $(gcc --print-libgcc-file-name)`/specs</userinput></screen>
-
-  <para>It is a good idea to visually inspect the specs file to verify the
-  intended change was actually made.</para>
-
-  <para>It is imperative at this point to ensure that the basic
-  functions (compiling and linking) of the adjusted toolchain are working
-  as expected. To do this, perform the following sanity checks:</para>
-
-<screen os="a"><userinput>echo 'int main(){}' &gt; dummy.c
-cc dummy.c -v -Wl,--verbose &amp;&gt; dummy.log
-readelf -l a.out | grep ': /lib'</userinput></screen>
-
-  <para os="b">There should be no errors,
-  and the output of the last command will be (allowing for
-  platform-specific differences in the dynamic linker name):</para>

-
-  <para>Note that on 64-bit systems <filename class="directory">/lib</filename> is
-  the location of our dynamic linker, but is accessed via a symbolic link
-  in /lib64.</para>

-  /lib/ld-linux.so.2.</para></note>
