* gcc.c (main): Don't run collect2 if we don't need to, as it slows
	  down compiles.
	  (process_command): Set repo_flag when -frepo is seen.
	  (repo_flag): Add.
	* doc/invoke.texi (-frepo): Add documentation explaining that
          -frepo is necessary on the link step for some compiles.

	* tlink.c (scan_linker_output): Add support for darwin linker, as it
	  emits unresolved symbols one per line, consuming entire line.
