Makefile: autobuild dependency rules
This uses gcc to generate dependency rules for each `.o` file, based on the corresponding `.c` file, into a new set of `.d` files (which are also defined to depend on the same set of source files as their `.o` files). Result: * all objectfile dependencies are correctly calculated * only the necessary dependencies are recalculated when a sourcefile is updated Inspiration for the build rules: * http://www.gnu.org/software/make/manual/make.html#Automatic-Prerequisites * http://make.paulandlesley.org/autodep.html Signed-off-by: Lars Hjemli <hjemli@gmail.com>
