From 150f500426b4bfe1c4b037c40d989a81aa3b6f9c Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Sun, 20 Jan 2013 12:58:22 +0000 Subject: arch: allow adding a suffix to the arch-part of a tuple For some architectures, it is legit to have an alternate value in the 'architecture' part of the tuple. For example: armv5te-* armv7a8-* Besides, some packages expect the tuple to reflect the arch variant (eg. openMPI) to detect the variant's capabilities (eg. atomic primitives). This patch adds an option for the user to specify a suffix to be added to the arch-part of the tuple.
