ghc-options in cabal.project file aren't applied

In my cabal.project file I have

```
packages: common, stub, client, dwarfadt, dwarf

package dwarf
ghc-options: -Werroradasdasd
```

So I expect that when I build the `dwarf` package, the extra options are passed to the package. However, it seems these options are completely ignored when running `cabal new-build dwarf`.

Perhaps there is a problem applying `ghc-options` to components?
