Subject: [PATCH v3 bpf-next 0/3] Fixes for bpftool-prog-profile

1. Fix build for older clang;
2. Fix skeleton's dependency on libbpf;
3. Add files to .gitignore.

Changes v2 => v3:
1. Add -I$(LIBBPF_PATH) to Makefile (Quentin);
2. Use p_err() for error message (Quentin).

Changes v1 => v2:
1. Rewrite patch 1 with real feature detection (Quentin, Alexei).
2. Add files to .gitignore (Andrii).

Song Liu (3):
  bpftool: only build bpftool-prog-profile if supported by clang
  bpftool: skeleton should depend on libbpf
  bpftool: add _bpftool and profiler.skel.h to .gitignore
