AUCTeX configuration, hardwiring etc...

Hi folks, I have decided that we won't need all those special options
after all.  Really none of them.

Why?  Because we can make do by just making everything relative to
lispdir, then using

make install-el # installs in ${lispdir}/preview
make lispdir=that install-elc
make lispdir=whatever install-startup

The only problem is that the startup file needs to do something like

(defvar TeX-lisp-directory
        (if (file-directory-p
              (expand-file-name "auctex" (file-name-directory load-file-name)))
            (expand-file-name "auctex" (file-name-directory load-file-name))
           @lisplispdir@))

Which is sick.  So maybe we need something like
--with-package-lispdir[=auctex]

as a configure option that will hardcode

      (expand-file-name "auctex" (file-name-directory load-file-name))
into @lisplispdir@

Sigh.
