Fixed errors about define with non-array parameters.

This takes care of errors like this during `make build`:

```
- ace/lib/oop.js has define(...) with non-array parameter. Ignoring requirement.
- ace/mode/xml.js has define(...) with non-array parameter. Ignoring requirement.
- ace/mode/text.js has define(...) with non-array parameter. Ignoring requirement.
- ace/tokenizer.js has define(...) with non-array parameter. Ignoring requirement.
- ace/mode/text_highlight_rules.js has define(...) with non-array parameter. Ignoring requirement.
- ace/lib/lang.js has define(...) with non-array parameter. Ignoring requirement.
```
