[PULL 01/13] Use long endian options for ppc64

[Cédric Le Goater]

From: Miroslav Rezanina <mrezanin@redhat.com>

GCC options pairs -mlittle/-mlittle-endian and -mbig/-mbig-endian are
equivalent on ppc64 architecture. However, Clang supports only long
version of the options.

Use longer form in configure to properly support both GCC and Clang
compiler. In addition, fix this issue in tcg test configure.
