You keep saying this, but it is not totally true, _especially_ when
this command is run from a high level in the source tree.

Ie, cd /usr/src; make depend all; does infact DTRT as first a full sweep
over the src tree creating .depends is run, then a full pass over the
tree running make all (at this point the .depends do exist).

There are several cases though that should be changed to:
make depend && make all.
