I don't understand the renaming from pei-aarch64-little to pei-aarch64.
The architecture supports both little and big endian so I would like the endianness to stay in the name.

Additionally this looks like it'll break efi support as the object mapping is now broken in objcopy, so please
undo the renaming and name the new object format with -little as we need to be able to tell from the name
which format it is.

Thanks,
Tamar
