[PATCH] configure: Use -mlittle-endian instead of -mlittle for ppc64

[mrezanin]

From: Miroslav Rezanina <mrezanin@redhat.com>

GCC options -mlittle and -mlittle-endian are equivalent on ppc64
architecture. However, clang supports only -mlittle-endian option.

Use longer form in configure to properly support both GCC and clang
compiler.
