+Subject: [PATCH libgpg-error] syscfg: Add ARC architecture
+
+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
