[PATCH] Initialize object file info before output streamer

[Nico Rieck]

r179494 switched to using the object file info to retrieve the default text section for some MC streamers. When outputting an object file and the MCPureStreamer is used, this text section is requested before the object file info is initialized due to the enabled AutoInitSections flag of the streamer.
