Documentation cleanups

 * Add the section describing the project feature to the table of
   contents
 * Change the formatting of titles in the section on the project
   feature
 * Mention that the section on project feature is obsolete since the
   feature has now been implemented
 * Remove the duplication about two different sections documenting
   basically the same thing : how to use the Buildroot toolchain.

-    <p>By default, the cross-compilation toolchain is generated inside
-    <code>build_ARCH/staging_dir/</code>. But sometimes, it may be useful to
-    install it somewhere else, so that it can be used to compile other programs
-    or by other users. Moving the <code>build_ARCH/staging_dir/</code>
-    directory elsewhere is <b>not possible if using gcc-3.x</b>, because there
-    are some hardcoded paths in the toolchain configuration. This works, thanks
-    to sysroot support, with current, stable gcc-4.x toolchains, of course. </p>
-
-    <p>If you want to use the generated gcc-3.x toolchain for other purposes,
-    you can configure Buildroot to generate it elsewhere using the
-    option of the configuration tool : <code>Build options -&gt;
-    Toolchain and header file location</code>, which defaults to
-    <code>$(BUILD_DIR)/staging_dir/</code>. </p>
