stable backport of patches fixing perf, libbpf and bpftools compilation with binutils 2.40

[Hauke Mehrtens]

Hi,

The following patches are fixing the compilation of perf, bpf_jit_disasm 
and bpftools with binutils 2.40.

commit cfd59ca91467056bb2c36907b2fa67b8e1af9952
Subject: tools build: Add feature test for init_disassemble_info API changes

commit a45b3d6926231c3d024ea0de4f7bd967f83709ee
Subject: tools include: add dis-asm-compat.h to handle version differences

commit 83aa0120487e8bc3f231e72c460add783f71f17c
Subject: tools perf: Fix compilation error with new binutils

commit 96ed066054abf11c7d3e106e3011a51f3f1227a3
Subject: tools bpf_jit_disasm: Fix compilation error with new binutils

commit 600b7b26c07a070d0153daa76b3806c1e52c9e00
Subject: tools bpftool: Fix compilation error with new binutils


Please backport these patches to kernel 5.15. Backporting them to 5.10 
resulted in more merge conflicts for me so I did not continue if it.


The patches are applying cleanly on top of 5.15.98 expect for a trivial 
merge conflict in the last one:
-----
--- a/tools/bpf/bpftool/Makefile
+++ b/tools/bpf/bpftool/Makefile
@@@ -76,7 -93,7 +76,7 @@@ INSTALL ?= instal
   RM ?= rm -f

   FEATURE_USER = .bpftool
- FEATURE_TESTS = libbfd disassembler-four-args reallocarray zlib libcap \
  -FEATURE_TESTS = libbfd disassembler-four-args 
disassembler-init-styled zlib libcap \
++FEATURE_TESTS = libbfd disassembler-four-args disassembler-init-styled 
reallocarray zlib libcap \
         clang-bpf-co-re
   FEATURE_DISPLAY = libbfd disassembler-four-args zlib libcap \
