[PATCH v6 0/4] Option to build big-endian with ELFv2 ABI

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.

Thanks,
Nick
