Before that, we add "$(obj)" and "$(src)" in as many places as possible where we will need to know which subdirectory is been built. "$(obj)" is for files been generated during the build, and "$(src)" is for files present in the source tree. For now, we set both to "." in Rules.mk and Makefile.clean. A few places don't tolerate the addition of "./", this is because make remove the leading "./" in targets and dependencies in rules, so these will be change later.
