As I said in my first email, when adding application fonts, the family names
returned by FcFreeTypeQueryFace is *NOT* sorted by locale, thus, I need to
find out which name is for the current locale myself. I can test each one
with their familylang, but how do I know the system familylang?

To be specific, what I need is FcGetDefaultLang() to be exported.

Because Qt has to build its own cross-platform font database, it's not
just about matching, it's also about providing the users an unified
font list.
