UPDATE: Not applicable, patch has changed with different commit. Ignore.

I've done a side-by-side comparison of the raw logs from this and a failed build and found the problem. This is from the successful run:

and the failed run:

Actually that failed run is from the new lwip version, ignore.

I will run this PR three times and if all is ok I will merge it as it is. I know it is not the best solution but better a workaround than having to run manually failed jobs.

I'm doing the same check but focussed on just the lwip2 component. If it works I'll open a PR.
