sdk-manual, ref-manual: New variable for including toolchain

Added a new variable description for SDK_INCLUDE_TOOLCHAIN.
Along with the new glossary entry, I updated a couple places
where it would be relevant to cross-reference the new variable.

(From yocto-docs rev: df99b097595e7488a93354082b8d9f33acd9c229)

+        You can explicitly control whether or not to include the toolchain
+        when you build and SDK by setting the
+        <ulink url='&YOCTO_DOCS_REF_URL;#var-SDK_INCLUDE_TOOLCHAIN'><filename>SDK_INCLUDE_TOOLCHAIN</filename></ulink>
+        variable.
+        When you set this variable to "1", you cause the toolchain to be
+        included even when <filename>SDK_EXT_TYPE</filename> is set to
+        "minimal".
