libtool.eclass: elibtoolize: add ppc64le handling #580792

1) We faced unable read SONAME from ${lib} when emerge below packages
   platform               pacakge                 elibtoolized
   ppc64le                app-text/opensp         no
   ppc64le                dev-libs/expat          yes
   ppc64le                net-firewall/iptables   yes
   ppc64le                net-libs/libmnl         no
   ppc64le                sys-apps/acl            yes
   ppc64le                sys-apps/attr           yes
   ppc64le                sys-libs/gdbm           yes
   ppc64le                sys-process/procps      no

2) The problem is due to the wrong $LD="ld -m elf64ppc" when link.
 This patch sets $LD="ld -m elf64lppc" in m4/libtool.m4 on ppc64le.

+this adds support for ppc64le to older versions.  most of this is upstream already.
