commit cfd59ca91467056bb2c36907b2fa67b8e1af9952 upstream.
binutils changed the signature of init_disassemble_info(), which now causes compilation failures for tools/{perf,bpf}, e.g. on debian unstable.
Relevant binutils commit:
https://sourceware.org/git/?p=binutils-gdb.git%3Ba=commit%3Bh=60a3da00bd5407...
This commit adds a feature test to detect the new signature. Subsequent commits will use it to fix the build failures.
