Daniel Verkamp 9ea5194634 build: simplify dependency generation
Modern GCC and Clang versions can generate .d files without needing the
complex sequence of sed scripts that we currently use.

Also adjust the .o rule so the .d file is regenerated if it gets
deleted.

Also make the .o depend on all of the Makefile fragments in
$(MAKEFILE_LIST) so that it is rebuilt if the Makefile is changed.
