make_bindist.sh broken

I need a distribution without shared libraries and was trying to run make_bindist.sh. There are a couple things currently breaking it, but running this fixed it for me:

```
rm data/HRV_wOG.nw
rm data/*.ipynb
```

I think because the Makefile.am has `data/*` it will treat everything in there as a target but these files that were presumably added later are causing it to fail
