Makefile: have "coccicheck" re-run if flags change
Fix an issue with the "coccicheck" family of rules that's been here
since 63f0a758a06 (add coccicheck make target, 2016-09-15), unlike
e.g. "make grep.o" we wouldn't re-run it when $(SPATCH) or
$(SPATCH_FLAGS) changed. To test new flags we needed to first do a
"make cocciclean".
This now uses the same (copy/pasted) pattern as other "DEFINES"
rules. As a result we'll re-run properly. This can be demonstrated
e.g. on the issue noted in [1]:
$ make contrib/coccinelle/xcalloc.cocci.patch COCCI_SOURCES=promisor-remote.c V=1
[...]
SPATCH contrib/coccinelle/xcalloc.cocci
$ make contrib/coccinelle/xcalloc.cocci.patch COCCI_SOURCES=promisor-remote.c SPATCH_FLAGS="--all-includes --recursive-includes"
* new spatch flags
SPATCH contrib/coccinelle/xcalloc.cocci
SPATCH result: contrib/coccinelle/xcalloc.cocci.patch
