Hmmm, it might depend on how libltdl was configured.  I've had a quick
scan over the ltdl.c  It will search for files ending in LTDL_SHLIB_EXT if
it does not find the .la file, but I think lt_dlopenext() needs to be used
for this to happen.  As I understand it, lt_dlopen() requires a filename
with an explicit suffix and does not search for alternatives.

I suppose another possibility is that some other environment variables
might be needed.

If I'm wrong here about the behaviour of lt_dlopen() or lt_dlopenext()
I'd like to know because it might break a few assumptions I've been making
(not being a libtool expert by any means).
