From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Paulo Flabiano Smorigo <pfsmorigo@linux.vnet.ibm.com>

Subject: [PATCH] Add powerpc little-endian (ppc64le) flags
libgcc dependency was removed *just* for this target because
the distros that use ppc64el doesn't have 32-bit support on it.
* configure.ac: Add targets for powerpc64el and skip libgcc.
* Makefile.am: Likewise.
