Add a build script to compile bpf source code. A program in restricted C is compiled into an object file. Object file is converted to BPF skeleton [0] header file. If build with custom meson build rule, the target header will reside in build/ directory (not in source tree), e.g the path for socket_bind: `build/src/core/bpf/socket_bind/socket-bind.skel.h` Script runs the phases: * clang to generate *.o from restricted C * llvm-strip to remove useless DWARF info * bpf skeleton generation with bpftool These phases are logged to stderr for debug purposes. To include BTF debug information, -g option is passed to clang. [0] https://lwn.net/Articles/806911/
