| 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. |
