Yah, this has come up in the past during review but the wrong version
somehow snuck in, sorry. ;-\

Can you guys verify this fixes the build issue? I don't have a ppc build
setup.

Thx.

Subject: [PATCH] tools/insn: Restore the relative include paths for cross
 building

Building perf on ppc causes:

  In file included from util/intel-pt-decoder/intel-pt-insn-decoder.c:15:
  util/intel-pt-decoder/../../../arch/x86/lib/insn.c:14:10: fatal error: asm/inat.h: No such file or directory
     14 | #include <asm/inat.h> /*__ignore_sync_check__ */
        |          ^~~~~~~~~~~~

Restore the relative include paths so that the compiler can find the
headers.
