documentation/dev-manual/dev-manual-kernel-appendix.xml: cleared up note

There is note instructing the user to delete unused .bbappend files
or comment out the COMPATIBLE_MACHINE statements in those unused
files before running the build in the example.  the note was not
clear about the COMPATIBLE_MACHINE statement in the .bbappend file
that is actually being used.  I edited the text to be clear about
that.
