lto-wrapper.c (debug_objcopy): Add rename parameter; pass it down to simple_object_copy_lto_debug_sections.


	* lto-wrapper.c (debug_objcopy): Add rename parameter; pass
	it down to simple_object_copy_lto_debug_sections.
	(run_gcc): Determine incremental LTO link time and configure
	lto1 into non-wpa mode, disable renaming of debug sections.
