No no, misunderstanding here:

Suppose I am writing some software package S.  It makes use of libltdl.
I do not want to ship the libltdl sources with it.  Rather, I want to
require the users of S to separately install libltdl on their system
(given software distributions with decent package dependency handling,
this might not be such a bad thing to do).  Does Libtool support this?
If so, then the documentation does not explicitly state this (and how
to achieve it).  It /seems/ to work for me if I use
  LTDL_CONVENIENCE
  LT_INIT
  LT_WITH_LTDL
and `libtoolize' without --ltdl.

The most annoying part about more testcases is that the comment about
ordering a pizza will soon be a major understatement.
