I have the same problem on my server, also aarch64-linux.  A minimal 
reproducer that fails on both my server and my laptop (x86_64-linux) is

     guix build -s aarch64-linux -e '
     (begin
      (use-modules (gnu bootloader)
                   (gnu bootloader grub))
      ((@@ (gnu bootloader grub) grub-background-image)
       (bootloader-configuration
        (bootloader grub-efi-bootloader))))
     '

I have tried bisecting it with this (see the attached log) and ended up 
at commit
     6975b1871b (gnu: rust-ring-0.17: Build source using trivial-build-system., 2024-12-15)
If I revert this commit and additionally
     584c79d5df (gnu: rust-ring-0.13: Build source using trivial-build-system., 2024-12-17)
     57be7a0184 (gnu: rust-ring-0.14: Build source using trivial-build-system., 2024-12-17)
     7db675130f (gnu: rust-ring-0.16: Build source using trivial-build-system., 2024-12-17)
(make fails when reverting only 6975b1871b) on top of commit
     87045f0982 (gnu: paritwine: Update to 0.2.1., 2025-01-17)
I get no error.  No idea what that has to do with grafts though.
