* collect2.c (lderrout): New variable.

	(collect_exit): Dump ldout to stdout.  Dump and unlink lderrout,
	if it is set, to stderr.
	(handler): Unlink lderrout if it is set.
	(dump_file): Add "to" parameter.  Change all callers.
	(main): Initialize lderrout.
	(collect_execute): Add errname parameter.  Change all callers.
	Rename redir parameter to outname.  Never pass
	PEX_STDERR_TO_STDOUT to pex_run.
	* collect2.h (collect_execute, dump_file): Update declarations.
	* tlink.c (tlink_execute): Add errname parameter.  Change all
	callers.
	(do_tlink): Check lderrout as well as ldout.
