Doh, I see it. It is the -DHAVE_STRLCPY test, of course. And it happens
only with a V=1 build, so actually there's not a build problem.

Hm, trying your patch ontop of acme's perf/core still shows CHK stuff
$ make -s tools/perf
DESCEND perf
CHK -fstack-protector-all
CHK -Wstack-protector
CHK -Wvolatile-register-var
CHK bionic
CHK libelf
CHK libdw
...
and that's because I'm doing the build from the toplevel repo and not in
perf/. If I switch to perf first, it is silent:
$ make -s
Makefile:809: No bfd.h/libbfd found, install binutils-dev[el]/zlib-static to
gain symbol demangling
Makefile:846: No numa.h found, disables 'perf bench numa mem' benchmark, please
install numa-libs-devel or libnuma-dev
$
Oh, and one more thing, there's tools/scripts/Makefile.include which
looks at -s already and perf/Makefile includes it so you probably want
to put your change there so that all tools use it.
Thanks.
