[gtkmm-documentation] Work around gnome-doc-utils.make VPATH problems

[Daniel Elstner <daniel src gnome org>]

commit bcb4f3e28290b6d6ee7f1bf899b262941bbff2e1
Author: Daniel Elstner <danielk openismus com>
Date:   Tue Aug 25 11:23:31 2009 +0200

    Work around gnome-doc-utils.make VPATH problems
    
    * docs/tutorial/Makefile.am (C/gtkmm-tut-with-examples.xml): Always
    put this generated file into the source tree, because the rules in
    gnome-doc-utils.make do not perform a correct VPATH search for the
    xml2po input file.
    (C/programming-with-gtkmm-pdf.xml): Run $(MKDIR_P) C to create the
    output directory if necessary.
