Resolves: rhbz#2190484
Build with system libbpf
New release: v1.25
Support for DW_TAG_unspecified_type more generally.
Make sure struct member offsets are in ascending order. Rust BTF needs this.
Support C atomic types (DW_TAG_atomic_type).
Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, for __rcu, __user, etc
Exclude functions with the same name (static functions in different CUs), inconsistent prototypes or not following calling convention.
Support 'pahole --lang=/--lang_exclude=asm'
Support --compile from DWARF in addition to from BTF.
Exclude RUST CUs in 'btfdiff', as those are not yet being BTF encoded.

Backport BTF fix needed for kernel kfuncs

Process DW_TAG_LLVM_annotation tags.
Initial support for DW_TAG_skeleton_unit.
Encode BTF_KIND_TYPE_TAG and BTF_KIND_DECL_TAG
Fix handling of percpu symbols on s390.
Use cacheline size to infer struct member alignment from BTF.
Add --skip_missing to not stop when not finding one of -C arguments.
Fix __attribute__((__aligned__(N)) printing alignment for struct members.
Fix nested __attribute__(__aligned__(N)) struct printing order.
New release: v1.24
Add support to BTF_KIND_ENUM64.
Support multithreaded BTF encoding.
Encode char type as signed in BTF.
Introduce --lang and --lang_exclude to pahole.
Introduce --compile to pahole.
Don't segfault when processing bogus files.

New release: v1.22
Resolves: rhbz#2010414
Introduce -j/--jobs option to specify the number of threads to use.
Multithreaded DWARF loading, requires elfutils >= 0.178.
Preparatory work for multithreaded BTF encoding, the focus for 1.23.
Allow encoding BTF to a separate file.
Show all different types with the same name, not just the first one found.
Stop assuming that reading from stdin means pretty, add --prettify.
Improve type resolution for the --header command line option.
Do not consider the ftrace filter when encoding BTF for kernel functions.
Lock calls to non-thread safe elfutils' dwarf_decl_file() and dwarf_decl_line().
Change hash table size to one that performs better with current typical vmlinux files.
Allow tweaking the hash table size from the command line.
Add --kabi_prefix to avoid deduplication woes when using _RH_KABI_REPLACE().
Add --with_flexible_array to show just types with flexible arrays.
Support btfdiff with a detached BTF file.
Introduce sorted type output (--sort).
Disable incomplete CTF encoder.

Rebuilt for IMA sigs, glibc 2.34, aarch64 flags
