Yeah, I don't know how these pieces all come together (or
don't come together, as the case may be).  Nevertheless, it
is true that make is apparently trying a 'make addext.o'
before that .depend file exists.  Perhaps this is a bug, or
maybe I'm just barking up the wrong tree...

I'm going to try a few more tests, and see if I can make some
sense out of this.

Given that 'make buildworld' is going to effectively do:
     cd /usr/src/rescue
     make obj
     [...other stuff...]
     cd /usr/src/rescue
     make includes
     [...other stuff...]
     cd /usr/src/rescue
     make depend
     [...other stuff...]

it would be nice if *that* 'make depend' could result in all
of these .depend files being created.  That is clearly not
the case at the moment.
