This is hopefully the final attempt. Luis was happy for the module
patch to go via the powerpc tree, so I've put the the ELFv2 for big
endian build patches into the series. Hopefully we can deprecate
the ELFv1 ABI

Since v5, I cleaned up patch 2 as per Christophe's review. And patch
4 I removed the EXPERT depends so it's easier to test. It's marked as
experimental, but we should soon make it default and try to deprecate
the v1 ABI so we can eventually remove it.

I did some builds and boot tested them in qemu fine.

Thanks,
Nick
