DocBook: use DOCBOOKS="" to ignore DocBooks instead of IGNORE_DOCBOOKS=1 



Instead of a separate ignore flag, use the obvious DOCBOOKS="" to ignore
all DocBook files. This is also in line with the Sphinx build being
ignored if a non-empty DOCBOOKS make variable is specified on the make
command line.

This replaces the IGNORE_DOCBOOKS introduced in
