[PATCH 0/4] tools/bpf: allow building with musl

[Dominique Martinet]

Hi,

I'd like to build bpftool on alpine linux, which is musl based.

There are a few incompatibilities with it, I've commented on each patch
when I could think of alternative solutions.

I've tested the patch on an x86_64 debian testing with no problem, so
didn't obviously break glibc builds, and the binaries built for alpine
seem to work on aarch64 as well.

  tools/runqslower: musl compat: explicitly link with libargp if found
  tools/bpf: musl compat: do not use DEFFILEMODE
  tools/bpf: musl compat: replace nftw with FTW_ACTIONRETVAL
  tools/bpf: replace sys/fcntl.h by fcntl.h
