libgpg-error: Add ARC support

Patch was posted on the mailing list. Awaits inclusion looks like. Fixes
long range build failures on the platform.

Updated Mirror list. The first two seem to not work.

+
+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
