ref-manual: Updates to "Variables" and "Building with No Dependencies"

There was some confusion over some things in these two sections.
I re-wrote them with the help of Paul Eggleton to be clear on
them.

-            If you really want to build a specific <filename>.bb</filename> file, you can use

-            This command form does not check for dependencies so you should use it
-            only when you know its dependencies already exist.
-            You can also specify fragments of the filename.

             You can use the <filename>-e</filename> BitBake option to
