cpu/ppc64_cpu: single core plus smt and upstream as a target

[sacsant]

This two patch series add following support:

Add upstream as a target for ppc64_cpu test
Add capabilities to download and compile upstream source for
powerpc-utils tools(ppc64_cpu).
Add a test case to validate following scenario:
A system with single online core along with consecutive smt
level change to ensure number of online cores do not change
