Add odo

``` 
==> make test
make: *** No rule to make target `test'.  Stop.
Error: odo: failed
Failed executing: make test 
```

If ``` make test ``` is part of the usual ``` make ```, ``` make install ``` process the same process isn't carried across to the testpath, so there's no ``` make ``` file to call from inside that sandbox. You can add the ``` make test ``` bit with the other make elements, but the formula itself will still need some form of test to ensure functionality.
