One option might be to try to lt_dlsym one of the hwloc symbols that you know you'll need in the plugin (or any public hwloc symbol, for that matter). If ltdl_sym gets NULL back for the hwloc global symbol, then the plugin should disqualify itself and have itself unloaded (perhaps with some way of reporting what/why it did that).
