This change reduces the risk of LADSPA plugins referencing Audacity symbols by using the RTLD_DEEPBIND flag when loading the plugins. It also addresses an issue specific to the "blop" plugins where they load their own libraries (without RTLD_DEEPBIND). A much better solution would be to change Audacity's default symbol visibility to "hidden" which would expose ONLY symbols specificially marked as visible.
