### Basic Information:

Printer Model: N/A  
 MCU / Printerboard: N/A (test/configs/atmega328.config)  
 `klippy.log` (build log instead)  
[build.log](https://klipper.discourse.group/uploads/short-url/gvN9xorar5QPXmgxjMgt5yHCaYz.log) (221.8 KB)

### Describe your issue:

When running scripts/build-ci.sh in a ubuntu jammy container (after running install-ci), during the atmega328 configuration, the following error appears

```auto
  Linking out/klipper.elf

collect2: error: ld returned 1 exit status
make: *** [Makefile:72: out/klipper.elf] Error 1

```

This prevents any later builds from running, and indicates that there is not enough room on the target hardware for the current version of klipper.

Reproduction steps

```auto
> podman run --rm -it ubuntu:jammy
# apt update
# apt install git wget curl sudo vim make
# curl -L https://github.com/Klipper3d/klipper/archive/refs/heads/master.tar.gz | tar -xvz -C /var/tmp
# cd /var/tmp/klipper-master
# ./scripts/ci-install.sh
# ./scripts/ci-build.sh

```

Interestingly, this appears to work as expected on 20.04 (focal). Maybe a dependency updated and pushed it over the edge?
