It probarly uses the build-in cache in make - and I see no easy way to
tell make not to use the cache in this case.
Could you try to replace "$(wildcard $@)" with something like:
$(shell if -f $@ echo Y; fi)
Untested - I'm not on a Linux box right now.
I tried the following w/o success:
$(obj)/uImage: $(obj)/vmlinux.gz
$(Q)rm -f $@
$(call if_changed,uimage)
@echo ' Image: $@' $(shell if [ -f $@ ]; then echo 'is ready';
else echo 'not made'; fi)
