Added ASSUME_PROVIDED and SANITY_REQUIRED_UTILITIES variable
place-holders.  There is no text there yet but they are there
for placeholders.

+        This class should be inherited by recipes whose upstream packages
+        invoke the <filename>texinfo</filename> utilities at build-time.
+        Native and cross recipes are made to use the dummy scripts provided
+        by <filename>texinfo-dummy-native</filename>, for improved performance.
+        Target architecture recipes use the genuine
+        Texinfo utilities.
+        By default, they use the Texinfo utilities on the host system.
+        <note>
+            If you want to use the Texinfo recipe shipped with the build
+            system, you can remove "texinfo-native" from
+            <link linkend='var-ASSUME_PROVIDED'><filename>ASSUME_PROVIDED</filename></link>
+            and makeinfo from
