Not only PTHREAD_*_INITIALIZER, but also some more ABI constraints
must be kept. It needs careful work, of course.

I still don't understand why it's better to integrate 1:1 thread into
libc. Just same thing can be achieved by separated libptherad, and it
must be cleaner and easier to enhanace libpthread implementation, even
for 1:1 case (e.g. trying enhanced 1:1 thread).
