This is for the other one, where I stamped this:

   perf bpf: Fix building perf with BUILD_BPF_SKEL=1 by default in more distros

   Arnaldo reported that building all his containers with BUILD_BPF_SKEL=1
   to then make this the default he found problems in some distros where
   the system linux/bpf.h file was being used and lacked this:

      util/bpf_skel/bperf_leader.bpf.c:13:20: error: use of undeclared identifier 'BPF_F_PRESERVE_ELEMS'
              __uint(map_flags, BPF_F_PRESERVE_ELEMS);

   So use instead the vmlinux.h file generated by bpftool from BTF info.

   This fixed these as well, getting the build back working on debian:11,
   debian:experimental and ubuntu:21.10:
