Indeed our binutils are still based on 2.23 branch and corresponding
patches were missing.

What I did I just copied your "851-PR-other-56780.patch" to
"package/binutils/arc-2014.12" folder and on host-binutils rebuild no
libiberty.a was put in "host/usr/lib64".

Care to send another patch that adds "851-PR-other-56780.patch" to
"package/binutils/arc-2014.12" or should I do it myself?
