Extended Description

Other missing locales cause the relevant tests to be 'UNSUPPORTED' instead of failing.

The failures that occurred for me are fixed in r258403 and a few additional ones are fixed in D16408.

Also, even with all the missing locales available there are two tests that fail when LANG=C is in the environment:

libc++ :: std/localization/locale.categories/category.ctype/locale.ctype.byname/types.pass.cpp
libc++ :: std/localization/locales/locale/locale.cons/char_pointer.pass.cpp

I don't recall why I have that so I'm trying a build without it.
