arch-power: Update hello test program
This updates the hello test program binary to an equivalent
64-bit little endian executable. Since this binary is built
with a recent toolchain, the kernel version provided by the
uname system call is ramped up to be able to meet the minimum
version required by glibc. This binary also uses the readlink
system call and the Move From Time Base (mftb) instruction.
So, placeholder code is added for these.
