binutils changed the signature of init_disassemble_info(), which now causes
perf and bpftool to fail to compile (e.g. on debian unstable).

Relevant binutils commit: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=60a3da00bd5407f07d64dff82a4dae98230dfaac

util/annotate.c: In function ‘symbol__disassemble_bpf’:

This is being discussed on the mailing list. See email thread for more details.
