This patch set reorganize current x86 related code in objtool, [1-3] move
arch-specific to arch files and extract some common codes and [4] fixes
a cross-compile problem.

It make objtool more arch-generic, which makes other patches on different
architectures easier to be reviewed and merged.

Tested on x86 with unwind on kernel and module context.

Rebased to:
tip/objtool/core:22682a07acc3 (objtool: Fix objtool regression on x32 
systems)

Chen Zhongjin (2):
   objtool: Add generic symbol for relocation type
   objtool: Specify host-arch for making LIBSUBCMD

Madhavan T. Venkataraman (2):
   objtool: Make ORC type code arch-specific
   objtool: Make ORC init and lookup code arch-generic
