AArch64: Add support for AArch64 EFI (efi-*-aarch64).users/ARM/efi-aarch64-support-binutils
This adds support for efi-*-aarch64 by virtue of adding a new PEI target
pei-aarch64-little. This is not a full tagret 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.
As such it's not valid for use with gas but only with objcopy.
Any magic number is based on the Microsoft PE specification [1].
