Current acceptance test will not run properly in powerpc environment due qemu target is different from arch, this usually matches, except with bi-endian architectures like ppc64. uname would return `ppc64` or `ppc64le` based `big` or `little` endian but qemu `target` is always `ppc64`. Let's handle it.
