make sampledata can't find machine-resources

[Huw Wilkins]

When running `make sampledata` using maas master it fails with:

```
$ make sampledata

```

It looks like I have a `/home/ubuntu/maas/src/machine-resources/src/machine-resources/` dir, but nothing for `amd64`.

I seem to have got things mostly working by doing:

cd src/machine-resources/
sudo make install

Then doing `make sampledata` finishes successfully.

However, doing `make all` now fails with:
