Subject: [PATCH bpf-next] tools: bpftool: add missing bpf_prog_linfo forward declaration

From: Stanislav Fomichev <[email-masked]>
Date: Wed, 19 Dec 2018 14:51:47 -0800

When building bpftool without HAVE_LIBBFD_SUPPORT I see the following
warnings:
main.h:164:23: warning: ‘struct bpf_prog_linfo’ declared inside
parameter list will not be visible outside of this definition or
declaration
          const struct bpf_prog_linfo *prog_linfo,
                       ^~~~~~~~~~~~~~

Move bpf_prog_linfo around so both HAVE_LIBBFD_SUPPORT and
!HAVE_LIBBFD_SUPPORT see it.

Fixes: b053b439b72ad152 ("bpf: libbpf: bpftool: Print bpf_line_info
during prog dump")
