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.

<title>Building with No Dependencies</title>
<para>
If you really want to build a specific <filename>.bb</filename> file, you can use
the command form <filename>bitbake -b &lt;somepath/somefile.bb&gt;</filename>.
This command form does not check for dependencies so you should use it
only when you know its dependencies already exist.
To build a specific recipe (<filename>.bb</filename> file),
you can use the following command form:
<literallayout class='monospaced'>
$ bitbake -b &lt;somepath/somerecipe.bb&gt;
</literallayout>
This command form does not check for dependencies.
Consequently, you should use it
only when you know dependencies already exist.
<note>
You can also specify fragments of the filename.
In this case, BitBake checks for a unique match.

You can use the <filename>-e</filename> BitBake option to
display the resulting environment for a configuration
when you do not specify a package or for a specific package when
you do specify the package.
If you want to show the environment resulting from parsing a single
recipe, use the <filename>-b recipename</filename> form.
display the parsing environment for a configuration.
The following displays the general parsing environment:
<literallayout class='monospaced'>
$ bitbake -e
</literallayout>
This next example shows the parsing environment for a specific
recipe:
<literallayout class='monospaced'>
$ bitbake -e &lt;recipename&gt;
</literallayout>
