I think it's just missing the right ENV magic as the other cross
images have, e.g.:

  ENV ABI "aarch64-linux-gnu"
  ENV MESON_OPTS "--cross-file=aarch64-linux-gnu"
  ENV RUST_TARGET "aarch64-unknown-linux-gnu"
  ENV QEMU_CONFIGURE_OPTS --cross-prefix=aarch64-linux-gnu-

For the normal debian based images these are added automatically by
refresh:

  def cross_build(prefix, targets):
      conf = "ENV QEMU_CONFIGURE_OPTS --cross-prefix=%s\n" % (prefix)
      targets = "ENV DEF_TARGET_LIST %s\n" % (targets)
      return "".join([conf, targets])
