(multiple_definition): Remove plugin_multiple_definition call. (notice): Remove plugin_notice call. * ldlang.c (lang_list_insert_after, void lang_list_remove_tail): Move. Delete prototype. (plugin_insert): New static var. (open_input_bfds): Only rescan libs after plugin insert point. (lang_gc_sections): Omit plugin claimed files. (lang_process): Set plugin_insert. Only rescan when plugin adds objects. * plugin.h (no_more_claiming): Declare. (plugin_notice, plugin_multiple_definition): Don't declare. * plugin.c: Formatting.
