question about `make clean'

[Tom Tromey]

Right now `make clean' cleans directories in the reverse of the order
it builds them.  This is mostly correct.  However, there are a couple
of automake PRs that point out that for subdir cleans it would be
better to clean depth first.  Right now we clean `.' before the
subdirs by default.

I'm inclined to make `.' a special case and always clean it after
cleaning all the subdirs.  In fact, I'm going to make this change.
I can't think of a time when this would be wrong.  Anybody?
