+Remove runtime library paths
+
+For some extensions (bsddb, sqlite and dbm), Python setup.py script
+hardcode a runtime path (rpath) into the extension. However, this
+runtime path is incorrect (because it points to the location of the
+library directory on the development machine) and useless (because on
+the target, all useful libraries are in a standard directory searched
+by the dynamic loader). For those reasons, we just get rid of the
+runtime paths in cross-compilation mode.
