PATCH 1/1 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:

PATCH 1/1 binutils: disable warning flags to prevent build failures

Hi all,

I submitted a patch to binutils that fixes the issue:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=c5da193232ea0452f714dffee0d417d965590476

So the workaround, proposed in the patch above, should be reverted after update to the upcoming binutils version.

Thanks.
