H.J. Lu dc2be3d2f6 x86: Generate PLT relocations for -z now

This patch partially reverses:

commit 25070364b0
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.
