- fix GN build with: git checkout 5d0a4153b0bcc86c5a23310d5b648a587be3c56d
While testing the addition of picotool to our docker image,
I noticed that GN with the latest commits from September
https://gn-review.googlesource.com/q/project:gn
fails to build and returns this error:

```
For now, as a workaround, I used
git checkout 5d0a4153b0bcc86c5a23310d5b648a587be3c56d
with a commit that does not cause errors in the build.
