Subject: [PATCH] gcc: Tweak arm multilib endian patch for baremetal
Date: Thu, 26 Mar 2015 23:55:12 +0000	[thread overview]
Message-ID: <1427414112.14020.170.camel@linuxfoundation.org> (raw)

In a baremetal build, TARGET_ENDIAN_OPTION isn't set leading to build
failures. Add in ifdefs to avoid this.

Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
