Stanislav Fomichev 29a9c10e41 bpftool: make libbfd optional ... Make it possible to build bpftool without libbfd. libbfd and libopcodes are typically provided in dev/dbg packages (binutils-dev in debian) which we usually don't have installed on the fleet machines and we'd like a way to have bpftool version that works without installing any additional packages. This excludes support for disassembling jit-ted code and prints an error if the user tries to use these features.
