When building with clang we get this error:
bench/numa.c:46:9: error: 'dprintf' macro redefined
[-Werror,-Wmacro-redefined]
#define dprintf(x...) do { if (g && g->p.show_details >= 1) printf(x); }
while (0)
^
/usr/include/bits/stdio2.h:145:12: note: previous definition is here
# define dprintf(fd, ...) \
^
CC /tmp/build/perf/tests/parse-no-sample-id-all.o
1 error generated.
So, make sure it is undefined before using that name.
