Hi all,

After merging the perf tree, today's linux-next build (native perf)
failed like this:

In file included from /usr/include/stdio.h:866,
from /home/sfr/next/next/tools/perf/util/branch.h:9,
from util/branch.c:2:
In function 'fprintf',
inlined from 'branch_type_stat_display' at util/branch.c:152:4:
/usr/include/powerpc64le-linux-gnu/bits/stdio2.h:105:10: error: '%8s' directive argument is null [-Werror=format-overflow=]
105 | return __fprintf_chk (__stream, __USE_FORTIFY_LEVEL - 1, __fmt,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
106 | __va_arg_pack ());
| ~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Presumably caused by commit

9781e500dcb8 ("perf branch: Extend branch type classification")

"native" here is PowerPC64 LE.
$ gcc --version
gcc (Debian 11.2.0-10) 11.2.0

I have used the perf tree from next-20220830 for today.
