[OE-core] [PATCH v2] binutils : enable x86_64-pep for producing EFI binaries

[Christopher Clark]

From: Christopher Clark <christopher.clark6 at baesystems.com>

On EFI architectures (arm/x86/x86_64/aarch64) add the x86_64-pep
emulation support to the linker to enable production of Portable
Executables for EFI binaries.

Enables building the EFI variant of the Xen hypervisor.
