Subject: [1/5] tools build: add feature test for init_disassemble_info API changes
Date: Sun, 3 Jul 2022 14:25:47 -0700
Origin: https://lore.kernel.org/lkml/20220703212551.1114923-2-andres@anarazel.de/
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.
