[Buildroot] [PATCH] binutils: disable warning flags to prevent build failures

binutils-arc-2016.09-eng008 build fails sometimes.

This happens due to the following issue:

binutils configure script has CC variable that stores compiler for
target and CC_FOR_BUILD variable that stores compiler for host.

WARN_FLAGS are verified by the script to be compatible only with CC
compiler but not with CC_FOR_BUILD compiler. Despite this WARN_FLAGS
are passed to both CC and CC_FOR_BUILD compilers. This leads to
unevident errors when cross-compiling. More information you can find
in the binutils mailing list:
https://sourceware.org/ml/binutils/2016-08/msg00117.html

We are going to write a patch for bunutils that fixes the initial
issue. Current patch contains temporary workaround. It should be
deleted after real fix.

Fixes:
