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 $ 1. https://lore.kernel.org/git/20220823095602.GC1735@szeder.dev/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>
