[ECOS] Can I also generate other outputs of gcc when build?

However, I have done it by add make steps to the 
"\packages\pkgconf\rules.mak". Such as:

%.o.d : %.c
ifeq ($(HOST),CYGWIN)
	@mkdir -p `cygpath -w "$(dir $@)" | sed "s@\\\\\\\\@/@g"`
else
	@mkdir -p $(dir $@)
endif
	$(CC) -c $(INCLUDE_PATH) -I$(dir $<) $(ACTUAL_CFLAGS) 
-Wp,-MD,$(@:.o.d=.tmp) -E -o $(dir $@)$(OBJECT_PREFIX)_$(notdir 
$(@:.o.d=.i)) $<
	$(CC) -c $(INCLUDE_PATH) -I$(dir $<) $(ACTUAL_CFLAGS) 
-Wp,-MD,$(@:.o.d=.tmp) -o $(dir $@)$(OBJECT_PREFIX)_$(notdir $(@:.o.d=.o)) 
$<
	@sed -e '/^ *\\/d' -e "s#.*: #$@: #" $(@:.o.d=.tmp) > $@
	@rm $(@:.o.d=.tmp)

So it can generate ".i" file for every ".c".

Thanks!
