From b15fbd4996ee1feedb524abfff7c581d885b51df Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 5 Oct 2010 14:08:55 +0200 Subject: 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.
