Subject: [PATCH] x86/defconfig: Enable WERROR

From: Borislav Petkov <bp@...e.de>

To quote Linus:

"EVERYBODY should have CONFIG_WERROR=y on at least x86-64 and other
serious architectures, unless you have some completely random
experimental (and broken) compiler.

New compiler warnings are not acceptable."

So this should make at least the most obvious and common ones not go
unnoticed.
