Subject: [Buildroot] [PATCH] binutils: fix bfin compile error
Date: Wed, 26 Apr 2017 19:48:02 +0200	[thread overview]
Message-ID: <20170426174802.GA30776@waldemar-brodkorb.de> (raw)

Newer gcc requires even lower optimization, only with -O0 we
can successfully compile binutils for the target.

Fixes:
