When linking a Go archive, if the archiver invocation is the very last thing that needs to happen in the link (no "atexit" cleanups required remove the locally created tmpdir) then call syscall.Exec to invoke the archiver command instead of the usual exec.Command. This has the effect of reducing peak memory use for the linker overall, since we don't be holding onto all of the linker's live memory while the archiver is running.
