[POWERPC] Select proper defconfig for crosscompiles

The trick for finding the right defconfig is neat, but you forgot to
provide an i686_defconfig.  ;-)

More seriously, cross compiling the defconfig is often useful, e.g. for
testing the compilation of patches that touch multiple architectures,
and this patch therefore chooses g5_defconfig if $(CROSS_COMPILE) is
non-empty.
