If you remove src/out/go-workspace here, then trying to move the bin dir to
src/out/go-workspace/bin below should fail, since shutil.move doesn't re-create
the src/out/go-workspace dir for you, I suppose? 

+  shutil.move(os.path.join(tmp_dir, 'bin'), go_bin_dir)
+  os.rmdir(tmp_dir)

 if __name__ == '__main__':
   sys.exit(main())
