From: Andres Freund <andres@anarazel.de>

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;a=commit;h=60a3da00bd5407f07

This commit adds a feature test to detect the new signature.  Subsequent
commits will use it to fix the build failures.
