Sure, that's probably right. However it's tough to tell. You could look for "\.so(\.|$)" or something. But that's encoding lots of details. I think that uses of dlopenext are already oblivious to `stat' calls, because they sanction looking for .la files before e.g. .so files, so it's not a problem to just do what the doc says: bare path first, then grovel extensions.
Use of .la files does not incur more stat calls unless the .la file is not present. Using .la files is really a better solution than what you are trying to do. The .la file format is just simple text so guile could construct its own .la files (or rename/link-to existing .la files) to load versioned libraries in a particular way.
Clearly libltdl is not matching its documentation and what you requested to do should have worked. Always keep in mind that there is a cost in terms of performance and security whenever libltdl looks in another place.
