Merge branch 'bpftool: Add LLVM as default library for disassembling JIT-ed programs'

Quentin Monnet says:

====================

To disassemble instructions for JIT-ed programs, bpftool has relied on the
libbfd library. This has been problematic in the past: libbfd's interface
is not meant to be stable and has changed several times, hence the
detection of the two related features from the Makefile
(disassembler-four-args and disassembler-init-styled). When it comes to
shipping bpftool, this has also caused issues with several distribution
maintainers unwilling to support the feature (for example, Debian's page
for binutils-dev, libbfd's package, says: "Note that building Debian
packages which depend on the shared libbfd is Not Allowed.").

This patchset adds support for LLVM as the primary library for
disassembling instructions for JIT-ed programs.

We keep libbfd as a fallback. One reason for this is that currently it
works well, we have all we need in terms of features detection in the
Makefile, so it provides a fallback for disassembling JIT-ed programs if
libbfd is installed but LLVM is not. The other reason is that libbfd
supports nfp instruction for Netronome's SmartNICs and can be used to
disassemble offloaded programs, something that LLVM cannot do (Niklas
confirmed that the feature is still in use). However, if libbfd's interface
breaks again in the future, we might reconsider keeping support for it.

v4:
- Rebase to address a conflict with commit 2c76238eaddd ("bpftool: Add
"bootstrap" feature to version output").

v3:
- Extend commit description (patch 6) with notes on llvm-dev and LLVM's
disassembler stability.

v2:
- Pass callback when creating the LLVM disassembler, so that the
branch targets are printed as addresses (instead of byte offsets).
- Add last commit to "support" other arch with LLVM, although we don't
know any supported triple yet.
- Use $(LLVM_CONFIG) instead of llvm-config in Makefile.
- Pass components to llvm-config --libs to limit the number of
libraries to pass on the command line, in Makefile.
- Rebase split of FEATURE_TESTS and FEATURE_DISPLAY in Makefile.
