grub segfault on x86-64 host when installing EFI for aarch64 target

Describe the bug

This is a rehash of the issue I banged my head against last year: https://discourse.nixos.org/t/nixos-install-and-nixos-enter-chroot-failed-to-run-command-nix-var-nix-profiles-system-activate-no-such-file-or-directory/32071

In short, grub2 from an x86_64 nixos host segfaults when trying to install an EFI bootloader to a aarch64-linux system.

Steps To Reproduce

Steps to reproduce the behavior:

I initially encountered when trying to nixos-install from an arch linux x86_64 host, but I thought the segfault might be due to a problem with binfmt_misc on Arch, so I tried with NixOS but ran into a similar crash. I think easiest to reproduce:

$ nix-shell -p 'let pkgs = import <nixpkgs> { system = "aarch64-linux"; }; in pkgs.grub2.override { zfsSupport = true; inherit (pkgs) zfs; }'
[nix-shell]$ sudo grub-install --efi-directory /mnt/zfs-root/boot/efi --boot-directory /mnt/zfs-root/boot --target arm64-efi --recheck --removable
Installing for arm64-efi platform.
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault

Expected behavior

Grub installation succeeds

Additional context

As linked above, I've had a super painful time trying to fix bootloaders on arm64 systems from x86 nixos hosts.
