Hi,
Building bpf programs with .BTF section,
I thought it'd be better to convert dwarf info to .BTF by
a new tool such as 'tools/bpf/bpf_dwarf2btf' instead of pahole
in the future.
Currently for bpf binary that have .BTF section,
we need to use pahole from https://github.com/iamkafai/pahole/tree

Currently, code at label *out* is unreachable. Fix this by updating

There must be a limit for "overlimit" to make sense. T
Commit 24dea04767e6 ("bpf, x32: remove ld_abs/ld_ind")
removed the 4 /* Extra space for skb_copy_bits buffer */
from _STACK_SIZE, but it didn't fix the concerned code
in emit_prologue and emit_epilogue, and this error will
bring very strange kernel runtime errors.
This patch fix it.

To smoothly test BTF supported binary on samples/bpf,
let samples/bpf/Makefile probe llc, pahole and
llvm-objcopy for BPF support and use them
like tools/testing/selftests/bpf/Makefile
