Subject: [PATCH 4.14 04/74] objtool: Fix cross-build

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Josh Poimboeuf <jpoimboe@...hat.com>

commit 9eb719855f6c9b21eb5889d9ac2ca1c60527ad89 upstream.

Stephen Rothwell reported this cross-compilation build failure:

| In file included from orc_dump.c:19:0:
| orc.h:21:10: fatal error: asm/orc_types.h: No such file or directory
| ...

Caused by:

  6a77cff819ae ("objtool: Move synced files to their original relative locations")

Use the proper arch header files location, not the host-arch location.
