The reasoning for changing that is:
  - there are two files with a GPLv2+ header;
    - gnuefi/crt0-efi-aarch64.S -> GPLv2+ or something like a BSD-2c
    - gnuefi/crt0-efi-arm.S     -> GPLv2+
  - all other files are BSD-3c (or have no licensing info)
  - we don't build gnuefi for ARM or AArch64, only for x86 or x86_64

However, re-reading README.gnuefi, we can read this:

---8<---
 gnuefi: This directory contains the glue necessary to convert ELF64
        binaries to EFI binaries.  Various runtime code bits, such as
        a self-relocator are included as well.  This code has been
        contributed by the Hewlett-Packard Company and is distributed
        under the GNU GPL.
---8<---

This is very confusing.Waht about changing to:

GNU_EFI_LICENSE = BSD-3c and/or GPLv2+ (gnuefi), BSD-3c (efilib)

Well, I mostly disagree there, if only by looking at the files we *do*
build (others we don't care).
