Build process updated:
You have to specify `TARGET` to specify a configuration, e.g.
```
rake TARGET=host-debug all test
```
When you port `mruby` to a new configuration:
1. copy an existing configuration under `target` directory
2. modify the new configuration file
3. build using the new configuration
4. send PR if you please
