x86: Generate PLT relocations for -z now
This patch partially reverses:
commit 25070364b0ce33eed46aa5d78ebebbec6accec7e
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sat May 16 07:00:21 2015 -0700
Don't generate PLT relocations for now binding
to support LD_AUDIT and LD_PROFILE with -z now. If there is an existing
GOT relocation, it is still used to avoid PLT relocation against the same
function symbol.
