I'm not sure this is necessary, the code that auto-reads .depend
(which is I presume the actual default) is not really needed
as the relevant rukes can be added to the makefile itself.

Unfortunately the reading of .depend, like the checks for the obj
subdirectory, can't be removed without breaking things.
