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

[Vlad Zakharov <Vladislav.Zakharov@synopsys.com>]

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.
