Right, I understand. But we are yet to hear about how this test
came about on powerpc server platforms. Will update 'powerpc'
arch listing above once we get some confirmation. May be once
this works on all relevant powerpc platforms, we can just merge
'powerpc' and 'ppc32' entries here as just 'powerpc'.
