Subject: [PATCH] Attempt to simulate the actions that Python itself uses for
 building extensions. * darwin-tools.jam; Added <link-format> to specify the
 type of linking to do. * python.jam; Adjust framework specification so that
 the added search path is correct. * python.jam; Change selection of library
 when building on MacOSX to always use the framework. * python.jam; Change
 adjustment of properties so that it builds Python extensions with link-format
 = bundle.
