   4 Subject: [PATCH 1/5] tools build: Add feature test for init_disassemble_info
   5  API changes
   6
   7 binutils changed the signature of init_disassemble_info(), which now causes
   8 compilation failures for tools/{perf,bpf}, e.g. on debian unstable.
   9
  10 Relevant binutils commit:
  11
  12   https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=60a3da00bd5407f07
  13
  14 This commit adds a feature test to detect the new signature.  Subsequent
  15 commits will use it to fix the build failures.
