ref-manual, overview-manual, Makefile: Moved toolchain concepts

Fixes [YOCTO #12370]

Moved the "Cross-Development Toolchain Generation" section from the
ref-manual to the overview-manual into the concepts chapter.  This
information is conceptual and now needs to live in the concepts
chapter of the new overview-manual.  Moving the section caused a
few links to have to be fixed in the ref-manual.  There was also a
figure in the section.  So, I had to move the figure from the ref-manual
to the overview-manual "figures" folder and update the Makefile for
the TARFILE generation.

+            For more information on toolchains, you can also see the

+            In the Yocto Project development environment, cross-development
+            toolchains are used to build the image and applications that run
+            on the target hardware.
+            With just a few commands, the OpenEmbedded build system creates
+            these necessary toolchains for you.

+            Most of the work occurs on the Build Host.
+            This is the machine used to build images and generally work within the
+            the Yocto Project environment.
+            When you run BitBake to create an image, the OpenEmbedded build system
+            uses the host <filename>gcc</filename> compiler to bootstrap a
+            cross-compiler named <filename>gcc-cross</filename>.
+            The <filename>gcc-cross</filename> compiler is what BitBake uses to
+            compile source files when creating the target image.
+            You can think of <filename>gcc-cross</filename> simply as an
+            automatically generated cross-compiler that is used internally within
+            BitBake only.
+            <note>
+                The extensible SDK does not use
+                <filename>gcc-cross-canadian</filename> since this SDK
+                ships a copy of the OpenEmbedded build system and the sysroot
+                within it contains <filename>gcc-cross</filename>.

+            You can use the OpenEmbedded build system to build an installer for

+            When you run the installer, it installs the toolchain, which contains

-        In the Yocto Project development environment, cross-development
-        toolchains are used to build the image and applications that run on the
-        target hardware.
-        With just a few commands, the OpenEmbedded build system creates
-        these necessary toolchains for you.

-        Most of the work occurs on the Build Host.
-        This is the machine used to build images and generally work within the
-        the Yocto Project environment.
-        When you run BitBake to create an image, the OpenEmbedded build system
-        uses the host <filename>gcc</filename> compiler to bootstrap a
-        cross-compiler named <filename>gcc-cross</filename>.
-        The <filename>gcc-cross</filename> compiler is what BitBake uses to
-        compile source files when creating the target image.
-        You can think of <filename>gcc-cross</filename> simply as an
-        automatically generated cross-compiler that is used internally within
-        BitBake only.
-        <note>
-            The extensible SDK does not use
-            <filename>gcc-cross-canadian</filename> since this SDK
-            ships a copy of the OpenEmbedded build system and the sysroot
