commit: https://git.buildroot.net/buildroot/commit/?id=19bf0087ec811571fa1a2d73439d52018a4ae19a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This enables support for ARC cores in numpy.
Cherry-picked from
https://github.com/numpy/numpy/commit/8edd610ffa3499eea3580f98f296ec80578fba73
Hopefully becomes a part of the next major release (like 1.14).

+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.
