[libvirt] [PATCH 1/4] PowerPC cpu: Add support for Power LE Architecture.

From: "Pradipta Kr. Banerjee" <bpradip(a)in.ibm.com&gt; Date: Tue, 7 Oct 2014 10:33:44 +0530 Starting PowerISA 2.07, Power architecture can run in little- endian mode as well. This adds support for PowerPC Little Endian architecture., and allows libvirt to spawn VMs in Little-Endian Mode. (conforming to 'ppc64le' architecture) Signed-off-by: Pradipta Kr.
