nx-X11/config/cf/{Imake.{cf,tmpl},{linux,xorg}.cf}: support ppc64le alongside ppc64(be).

On PPC64*, X_BYTE_ORDER was hardcoded to X_BIG_ENDIAN. Since the CPUs
support both modes and we actually intend to execute nxagent on ppc64le
as well, detect the actual endianess and add support for
Ppc64LeArchitecture.
