Makefile.in: Define a vpath for %.texi.

2003-10-24  Kelley Cook  <kcook@gcc.gnu.org>

	* Makefile.in: Define a vpath for %.texi.  Remove explicit $(docdir)
	and $(docdir)/include from any *.texi dependencies.
	($(docobjdir)/%.dvi): Depend on stmp-docobjdir.
	($(docobjdir)/%.1): Depend on .pod instead of .texi.
	($(docobjdir)/%.7): Likewise.
	(%.pod): New implicit rule.
	(cpp.pod): New dependency only rule.
	(gcc.pod): New intermediate rule with dependencies and commands.
	(gfdl.pod): Likewise.
	(fsf-funding.pod): Likewise.
