Previously there were hardcoded "x64" in EFI loaders' filenames.

Thanks for looking at this. I knew this would come up at some point!
Your patch looks good, except:

I don't really want this file to turn into an unstructured list of
global constants, but I think there might be a better way:
Nixpkgs already has an unexposed mapping of Nixpkgs platforms to EFI
architecture names[1], so it would be a shame to have to duplicate it
ourselves. What if instead, we moved that list somewhere accessible in
Nixpkgs, like how Nixpkgs already exposes the Linux and QEMU names for
architectures[2]? Then we could just access stdenv.hostPlatform.efiArch
or whatever in our Nix expressions, and so could Nixpkgs.
I imagine that'd be a welcome (and small) Nixpkgs refactoring, and I'd
gladly backport it to Spectrum's Nixpkgs immediately after it was
accepted upstream.

I've merged your Nixpkgs PR (#193175 for anybody following along at
home), and backported it to Spectrum's Nixpkgs as commit
5e6b4a3127b59be1c10e8e1ccf4b57db7ff3cca0.
