commit c1f351903d79593d1a794dbe138df2328755aca6
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri May 15 09:06:50 2020 -0700
x86: Also check if -fcf-protection works
When defaulting CET run-time support to auto, check if -fcf-protection
works. Even if the stage1 GCC doesn't support -fcf-protection, since
the final GCC does, CET run-time support will be enabled by default if
binutils support CET.
