If in some directory we have a dependency on 31# a file in another dir (which doesn't happen often, but it's often 32# unavoidable when linking the built-in.o targets which finally 33# turn into vmlinux), we will call a sub make in that other dir, and 34# after that we are sure that everything which is in that other dir 35# is now up to date. 36# 37# The only cases where we need to modify files which have global 38# effects are thus separated out and done before the recursive 39# descending is started.
