documentation/kernel-manual/kernel-how-to.xml: Updated build strategy

This section used the term "tree construction" somewhat out of context.
The section really focuses on what the build process and the user does
prior to compilation.  I changed wording to indicate the tree is
validated to be sure that the SRC_URI point to the right stuff and
that the BSP build branch exists.
