documentation: Created cross-references to new KMACHINE glossary item

With the creation of a new KMACHINE glossary item, there were two
areas in the YP doc set that reference the variable.  I added
cross-reference tags.  Also noted that some other references
were missing to the variable COMPATIBLE_MACHINE.
