Thanks, I've updated and added your Tested-by. I'll give sfr a chance to
test and queue it tomorrow.

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.

Fixes: 93281c4a9657 ("x86/insn: Add an insn_decode() API")
