Martin Waitz 71f95cfbcf [PATCH] DocBook: revert xmlto use for .ps and .pdf documentation
As xmlto doesn't work for print documentation, we need docbook-utils again for
these targets.

This patch allows the user to choose the method he wants to use.  (I'm still
hoping that someone will fix passivetex ;-)

# This makefile is used to generate the kernel documentation,

# See Documentation/kernel-doc-nano-HOWTO.txt for instruction in how
# to ducument the SRC - and how to read it.
# To add a new book the only step required is to add the book to the
# list of DOCBOOKS.
