From d4fd6975671477721936060771aa4d7d07fb0910 Mon Sep 17 00:00:00 2001
From: Werner Koch <wk@gnupg.org>
Date: Tue, 18 Sep 2018 14:54:08 +0200
Subject: [PATCH libgpg-error] syscfg: Support ARC CPUs and simplify aliasing
 table.

* src/mkheader.c (xmalloc): New.
(xstrdup): Implement using xmalloc.
(canon_host_triplet): Add supporr for arc CPU.  Adjust alias table to
also alias *-pc-*.  Rename ibm to unknown. Add internal arg.  Add
unknown vendor hack.
(main): New mode to just print the canonicalized form.
* src/Makefile.am (lock_obj_pub): s/-(pc|ibm)-/-unknown/.  Also rename
files accordingly.
--

config.sub does no real aliasing and thus we would need to add several
vendors to the alising tables despite that this has no technical
meanding.  Instead we now replace the vendor with "unknown" for the
4-part-"triplets".  This change will make maintenace easier.

Signed-off-by: Werner Koch <wk@gnupg.org>
