This section was largely redundant now. The small things that did
add value I placed in other areas of the chapter 2. One was a new
section on expanding variables using bitbake -e. Another was a bit
about the defconfig file. And a small procedure on how to create
config fragments using the "diffconfig" command was retained.
Links from the dev-manual and the ref-manual were adjusted as well.
