[ CC Andres F. + bpf folks ]

The patch-series from Andres Freund from [1] fixes the issue for me on
Debian/unstable AMD64:

[PATCH v1 0/3] tools: fix compilation failure caused by
init_disassemble_info API changes
[PATCH v1 1/3] tools build: add feature test for init_disassemble_info
API changes
[PATCH v1 2/3] tools: add dis-asm-compat.h to centralize handling of
version differences
[PATCH v1 3/3] tools: Use tools/dis-asm-compat.h to fix compilation
errors with new binutils

Compile-tested only (LLVM-14 x86-64).

Andres, you have some test-cases how you verified the built perf is OK?

Thanks, Andres.
