Makefile: don't create a ".build/.build/" for cocci, fix output
Fix a couple of issues in the recently merged 0f3c55d4c2b (Merge branch 'ab/coccicheck-incremental' into next, 2022-11-08): In copying over the "contrib/coccinelle/" rules to ".build/contrib/coccinelle/" we inadvertently ended up with a ".build/.build/contrib/coccinelle/" as well. We'd generate the per-file patches in the former, and keep the rule and overall result in the latter. E.g. running: make contrib/coccinelle/free.cocci.patch COCCI_SOURCES="attr.c grep.c" Would, per "tree -a .build" yield the following result: .build ├── .build │   └── contrib │   └── coccinelle │   └── free.cocci.patch │   ├── attr.c │   ├── attr.c.log │   ├── grep.c │   └── grep.c.log └── contrib └── coccinelle ├── FOUND_H_SOURCES ├── free.cocci └── free.cocci.patch Now we'll instead generate all of our files in ".build/contrib/coccinelle/". Fixing this required renaming the directory where we keep our per-file patches, as we'd otherwise conflict with the result. Now the per-file patch directory is named e.g. "free.cocci.d". And the end result will now be: .build └── contrib └── coccinelle ├── FOUND_H_SOURCES ├── free.cocci ├── free.cocci.d │   ├── attr.c.patch │   ├── attr.c.patch.log │   ├── grep.c.patch │   └── grep.c.patch.log └── free.cocci.patch The per-file patches now have a ".patch" file suffix, which fixes another issue reported against 0f3c55d4c2b: The summary output was confusing. Before for the "make" command above we'd emit: [...] MKDIR -p .build/contrib/coccinelle CP contrib/coccinelle/free.cocci .build/contrib/coccinelle/free.cocci GEN .build/contrib/coccinelle/FOUND_H_SOURCES MKDIR -p .build/.build/contrib/coccinelle/free.cocci.patch SPATCH .build/.build/contrib/coccinelle/free.cocci.patch/grep.c SPATCH .build/.build/contrib/coccinelle/free.cocci.patch/attr.c SPATCH CAT $^ >.build/contrib/coccinelle/free.cocci.patch CP .build/contrib/coccinelle/free.cocci.patch contrib/coccinelle/free.cocci.patch But now we'll instead emit (identical output at the start omitted): [...] MKDIR -p .build/contrib/coccinelle/free.cocci.d SPATCH grep.c >.build/contrib/coccinelle/free.cocci.d/grep.c.patch SPATCH attr.c >.build/contrib/coccinelle/free.cocci.d/attr.c.patch SPATCH CAT .build/contrib/coccinelle/free.cocci.d/**.patch >.build/contrib/coccinelle/free.cocci.patch CP .build/contrib/coccinelle/free.cocci.patch contrib/coccinelle/free.cocci.patch I.e. we have an "SPATCH" line that makes it clear that we're running against the "{attr,grep}.c" file. The "SPATCH CAT" is then altered to correspond to it, showing that we're concatenating the "free.cocci.d/**.patch" files into one generated "free.cocci.patch" at the end.
