+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.
