I'm now making it go thru the container builds.

Not a good start, checking:

[perfbuilder@five ~]$ time dm
   1    50.25 almalinux:8                   : FAIL clang version 12.0.1 (Red Hat 12.0.1-4.module_el8.5.0+1025+93159d6c)
    builtin-stat.c:1499:31: error: unused function 'perf_env__get_cpu' [-Werror,-Wunused-function]
    static inline struct perf_cpu perf_env__get_cpu(void *data, struct perf_cpu_map *map, int idx)

                                   ^
Interesting, it builds with gcc, not with clang:

+ make PYTHON=python3 ARCH= CROSS_COMPILE= EXTRA_CFLAGS= -C tools/perf O=/tmp/build/perf CC=clang

And it really isn't used anywhere in builtin-stat.c, will remove it
after figuring out when it stops being used.
