        Possible fix for bug #590

        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.
