Portability fix:

* POSIX syntax is 'include Makefile.depend', not '.include "Makefile.depend"'
* gmake(1) runs the build rule for the included file (duh), so delete the rule
* consequently, we have to mark the 'depend' maintainer target .PHONY
* as it's now .PHONY anyway, drop some prerequisites that are now useless
