oliverschmidt 7a228fea41 Replaced classic approach of generating dependency files via rule with generating them as side effect of generating object files. The issue with "No rule to make target ..." is solved as suggested in http://make.paulandlesley.org/autodep.html.
At least with gcc (and cc65) the dependency files are generated without an additional run of the C compiler. This is especially beneficial on Cygwin because of the fork() performance issue.
