guix system disk-image failure aarch64 -> armhf

[Andreas Enge]

Hello,

when issuing the following command on an aarch64 machine:
   guix system disk-image --system=armhf-linux config.scm
it fails like this:
building /gnu/store/p9iz58wrxc4jiqd21n1q0rwcrjgbrk3q-partition.img.drv...
Backtrace:

The appearance of "efi" and "grub" is suspicious.

I do have this in my config:
  (bootloader (bootloader-configuration
               (bootloader u-boot-novena-bootloader)
               (target "/dev/mmcblk0")))
So there is no trace of grub or efi in it. Does anyone know what is happening?
