Title: More user friendly configuration error message

If it cannot find `friso.init` in configure process, it makes configure error.
Default error message can not be said that there is sufficient information to resolve configuration error.

Before:

```log
configure: error: ""
```

After:

```log
configure: error: "Could not find friso.ini. Please specify friso.ini PATH with '--with-friso-ini=PATH'"
```
