Newer versions of 'shim' on aarch64 need a binutils whose objcopy
can create EFI PE images for the aarch64 arch.  This patchset adds
exactly that.  Came in as part of a shim fix, bsc#1198458 .

Subject: [PATCH] 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:
