When doing an in source build, $(OUTPUT) is empty so the rule has the same input and output file. Suppress the warning by only adding the rule when doing an out of source build. The same condition already exists for the clean rule for json files. This fixes the following warnings: make[3]: Circular pmu-events/arch/nds32/mapfile.csv <- pmu-events/arch/nds32/mapfile.csv dependency dropped. make[3]: Circular pmu-events/arch/powerpc/mapfile.csv <- pmu-events/arch/powerpc/mapfile.csv dependency dropped. ...
