From 9a225e7d4fb1de5c99c6b5b17cae2fc4c2d1c59a Mon Sep 17 00:00:00 2001
From: Alexey Brodkin <abrodkin@synopsys.com>
Date: Fri, 15 Sep 2017 11:59:14 +0300
Subject: [PATCH] Add support of ARC
Synopsys DesignWare ARC Processors are a family of 32-bit CPUs
which in some configurations may run Linux kernel and full stack
of applications on top of it. Among other things is Python.
With that change we allow building and usage of Numpy on ARC.
