So here's a patch to fix the actual bug.  Please try it.  It makes the
test pass on GNU/Linux.  OK to apply?  Should I rename `attempt', say,
to `filename_ext'?

Cheers,
Ralf

        * libltdl/ltdl.c (try_dlopen): Use `attempt' rather than
        `filename', as the former has the needed extension when called
        by lt_dlopenext.
