Ok got it.

Subject: [PATCH] bootloader: extlinux: Stop using dd binary.
* gnu/bootloader/extlinux.scm (dd): Remove it,
(install-extlinux): replace dd call by Guile I/O procedures.
* gnu/system/vm.scm (qemu-image): Add (ice-9 binary-ports) to used-modules
list to provide "get-bytevector-n" and "put-bytevector".
* guix/scripts/system.scm (bootloader-installer-derivation): Ditto.
