[powerpc] possible fix for ARCH=powerpc ...

[Sven Luther <sven.luther@wanadoo.fr>]

tags 340629 + patch
thanks

hi Manoj, ...

I wrote this fully untested powerpc.mk file, which i believe should replace
the ppc.mk and ppc64.mk for kernel versions >=2.6.15, not sure how to best do
this, but it is a need-fix for the 2.6.15 kernel release.

I believe it will not work as is out of the box, as these box will still
advertize as ppc and ppc64 system, not as powerpc ones, even if we now use
ARCH=powerpc.

Friendly,

Sven Luther
