Yes.  tex-site.el is placed in an arbitrary startup directory,
probably a directory intended for automatic installation.  auctex is
not necessarily below it.

But it would be fine with me if we have a default of

lispauctexdir='(expand-file-name "auctex" (file-name-directory load-file-name))))'

in our configure.in that only gets overriden when an _explicit_
--with-auctexdir is specified on the command line, so that
configure.in has the defaults

lispauctexdir='(expand-file-name "auctex" (file-name-directory load-file-name))))'
auctexdir='${lispdir}/auctex'

but an explicit -with-auctexdir will override _both_ using the current
mechanism.

This would mean that startup files (tex-site.el and preview-latex.el)
get installed in lispdir, and the bulk of the stuff gets installed in
auctexdir & previewdir, which default to '${lispdir}/auctex' and
'${lispdir}/preview' with auto-detection code relative to the
installation as you suggested, but which can be overriden on the
command line of configure, in which case the autodetection gets
replaced by the lisp-quoted explicit path.

That should cater for most things.  The XEmacs package system could
probably not be catered for just with ./configure options, but since
we have an explicit --with-packagedir option, this could also change
the lispauctexdir and auctex variable _defaults_ to something
appropriate pseudo-relative.

Package systems like RedHat and Debian install into fixed paths, so
the explicit --with-auctexdir generating an absolute path will always
be fine.
