Then I'm not sure what the point of your previous mail was, what did I

The point was for people who don't know ELFv2 has a specific meaning for 
powerpc, then ELF ABIv2 is more explanatory about it being an abi change
rather than base elf change, even if it's not the "correct" name.

toolchain and other docs.
