    AArch64: Add support for AArch64 EFI (efi-*-aarch64).

    This adds support for efi-*-aarch64 by virtue of adding a new PEI target
    pei-aarch64-little.  This is not a full target and only exists to support
EFI
    at this time.

    This means that this target does not support relocation processing and is
mostly
    a container format.  This format has been added to elf based aarch64
targets
    such that efi images can be made natively on Linux.

    However this target is not valid for use with gas but only with objcopy.

    With these changes the resulting file is recognized as an efi image by
    third party tools:
