Typically, that doesn't work for main programs because the link editor
will resolve weak unexported symbols to zero.  There might not be a
dynamic symbol entry for __pthread_key_create in this case.  Shared
objects are different in this regard.

I think interoperability for these mismatches has to come directly
from the mutex implementation.
