For bootstrap, update-subdirs and autoloads can execute in
parallel. autoloads will run another make to do update-subdirs.
If "autoloads" creates subdirs.el first while "update-subdirs" is not
running, it is possible that later "update-subdirs" deletes subdirs.el
while "autoloads" is using it. Am I off base here?
