I hit this same problem today while testing a build on a Debian amd64
machine.  I still don't know why the problem shows up on some machines
and not others, but as you suggest, modifying libguile/Makefile.am to
add a direct dependency on libguile-ltdl seems to fix the problem,
i.e.:

  guile_LDADD = libguile.la @abs_top_builddir@/libguile-ltdl/libguile-ltdl.la
  
So unless there are objections, I'll commit this to 1.6.

It would be interesting to see if the latest libtool behaves the same
way.  I have libtool 1.5.6 here (from Debian unstable), but the
upstream has released 1.5.10.

Oh, and Marius, unless you think I've misdiagnosed, I'll probably also
revert the addition of libguile-ltdl to subdirs_with_ltlibs in
pre-inst-guile.in.  Since these dirs are only added to the
LTDL_LIBRARY_PATH, and since LTDL_LIBRARY_PATH only affects
libguile-ltdl, and since there are no lt_dlopened libs in
libguile-ltdl, it seems like libguile-ltdl probably doesn't belong in
subdirs_with_ltlibs.
