STDCXX-970 and locale tests

[Liviu Nicoara]

While checking for fallout from 1072 I stumbled upon the collate test and its 
numerous (unrelated to 1072) failures. While I am looking at it I have a 
question: it seems to me that the locale tests do not test against STDCXX locale 
database. Is that right? So, all locale tests are supposed to be run without 
RWSTD_LOCALE_ROOT defined?

Thanks,
Liviu
