This has all been discussed before; see this email and others in the
thread:

http://www.openwall.com/lists/musl/2016/05/11/8

Masanori Ogino was going to work on some follow-up research, testing,
and/or implementation but didn't get around to it. I'm not aware of
any newer findings that contradict the direction suggested in that
thread.

For your specific examples, de_DE@...o would be searched in de_DE,
de@...o, and finally de; zh_CN.GBK would be invalid (non-UTF-8
encodings not permitted) but it's not clear to me how it should be
handled (rejection or rewriting at setlocale time, stripping .GBK at
translation load time, or leaving .GBK there and letting translation
fail).
