[PATCH v2 0/5] objtool: Reorganize x86 arch-specific code

[Chen Zhongjin]

This patch set reorganize current x86 related code in objtool, [1-3] move
arch-specific to arch files and extract some common codes, [4] fixes a
cross-compile problem and [5] fixes a call destination search bug.

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.
