bitbake: bitbake-user-manual: Added a note providing examples of task dependencies

Browse Source 
Fixes [YOCTO #9861]

In the "Dependencies internal to the .bb File" section, I placed a
note providing more detail on how recipes are built regarding task
dependency.

task.
And, the <filename>do_build</filename> depends on the completion
of the <filename>printdate</filename> task.
<note>
Recipes are built by having their
<filename>do_build</filename> (not to be confused with
<filename>do_compile</filename>) tasks executed.
For a task to run when a recipe is built, the task must
therefore be a direct or indirect dependency of
<filename>do_build</filename>.
For illustration, here are some examples:
<itemizedlist>
<listitem><para>
The directive
<filename>addtask mytask before do_build</filename>
causes <filename>mytask</filename> to run when the
recipe is built.
In this example, <filename>mytask</filename> is run
at an unspecified time relative to other tasks within
the recipe, since "after" is not used.
</para></listitem>
<listitem><para>
The directive
<filename>addtask mytask after do_configure</filename>
by itself does not cause <filename>mytask</filename>
to run when the recipe is built.
The task can still be run manually using the following:
<literallayout class='monospaced'>
$ bitbake <replaceable>recipe</replaceable> -c mytask
</literallayout>
<filename>mytask</filename> could also be declared as
a dependency of some other task.
Regardless, the task is run after
<filename>do_configure</filename>.
