autotools patches for --*dir and upcoming versions

[Daniel Mierswa <impulze at impulze dot org>]

Hi there
I created a patch to let the --{dataroot,doc,pdf,html}dir to be passed 
through configure instead of using the self written --with-*dir.
The patch also fixes some warnings spilled out by newer autotools 
regarding ordering of AC_ macros and unquoted definitions.
The patch was created against the official 6.8 tarball.
Tested by invoking the usual, autoreconf procedures, followed by 
./configure with --docdir=/something and invoking make install-html at 
the very end.
I'd like to hear your opinion.
The ChangeLog entries would be as follows:

2008-11-15  Daniel Mierswa  <impulze@impulze.org>
   * configure.ac: use config directory for m4-macro searches, provide
   AC_PROG_LIBTOOL, so ltmain.sh and others get updated by autoreconf,
   remove self-written --with-{dataroot,doc,pdf,html}dir switches and 
let the
   ones created by autoconf pass through, remove unneeded AC_SUBST
