[PATCH libgpg-error] syscfg: Add ARC architecture

[Alexey Brodkin]

From: Mylene Josserand <mylene.josserand at bootlin.com>

DesignWare ARC Processors are a family of 32-bit CPUs from Synopsys.
This change allows us to build for and use libgpg-error on ARC cores.

These values were obtained from a test application executed on ARC
in simulation this way:

1. Instructions for cross-compilation used are here:
   http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgpg-error.git;a=blob;f=README

2. Commands used on host:
   # build="$(build-aux/config.guess)"
   # ./configure --prefix=build/tmp-uclibc/sysroots/nsimhs/usr/ --host=arc-oe-linux-uclibc --build=$build
   # cd src
   # make gen-posix-lock-obj

3. Commands used on target:
   # ./gen-posix-lock-obj
