Makefile: fix parallel build
During parallel build, the top Makefile spawns multiple sub-makes for targets in cpu/$(CPU) and $(dir $(LDSCRIPT)). If the .depend files are not present in these directories, the sub-makes may end up generating these files simultaneously which leads to corrupted content. A typical error message is: .depend:39: *** multiple target patterns. Stop. This patch serializes the creation of .depend in cpu/$(CPU) and $(dir $(LDSCRIPT)) by adding these directories to the depend target in the top Makefile. Other directories in $(LIBS) are not affected since they contain only one Make target and thus only one sub-make is spawned per directory.
