That didn't actually work for me?

The duplication of these is caused by the second definitions being
inside an "if PPC64" block.

For PAGE_OFFSET and KERNEL_START we want the 2nd definitions, the
default value is different between 32 & 64 bit.

For RELOCATABLE it's a little weird, but we want the 2nd definition
because the depends condition is different between 32 & 64bit - though
they could probably be merged.

I don't really see why we need two versions of PHYSICAL_START.
