These are known failures (functionality not implemented on x86_64
yet). But it shouldn't impact the common use cases (local unwinding).
The larger issue libunwind faces is due to APIs that call malloc or
ones which take locks:

* dl_iterate_phdr
* pthread_setspecific

The latter is easy to work around. The former requires a lock free,
malloc free implementation of dl_iterate_phdr.
