rules.mk: make sure we always create a .depend file
There are some cases where "make depend" would always run when entering a directory. This happened when both the $(SRCS) and $(HOSTSRCS) lists were empty (which is for example typical for the examples/api/ directory). Avoid this by making sure that a ".depend" file gets always created, even if empty. Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
