[Buildroot] [PATCH] binutils: arc: fix custom patch

[Vlad Zakharov]

This commit fixes another brown-paper-bag issue that I've introduced by
my following patch:
toolchain: Bump ARC tools to arc-2017.03-rc1
(5f8ef7e25c5cc5c2e4ae4c8b6e8caa029ddf9a94)

arc-2017.03-rc1 differs a bit from 2.28. And so corresponding
of-the-tree patch should be updated appropriately.

Fixes target binutils build for arc:
