For ISAR, it looks like I'm using a patched version of this 2022 commit at 
the moment 
https://github.com/ilbers/isar/commit/20af1e2798353b118fc3538da0d4cdd8866101d5 
but due to upgrade to something more recent.

The `log.do_populate_sdk` file for this image recipe contains:
```
DEBUG: Executing shell function do_populate_sdk

```
so it's interesting that there are so many errors here when it's looks 
happy during the build!
