    python-cryptography: add -pthread to LD_FLAGS
    
    The OpenSSL bindings require pthread to avoid runtime issues that end in stack traces:
    
    File "/usr/lib/python2.7/site-packages/OpenSSL/__init__.py", line 8, in <module>
        from OpenSSL import crypto, SSL
      File "/usr/lib/python2.7/site-packages/OpenSSL/crypto.py", line 16, in <module>
        from OpenSSL._util import (
      File "/usr/lib/python2.7/site-packages/OpenSSL/_util.py", line 6, in <module>
        from cryptography.hazmat.bindings.openssl.binding import Binding
      File "/usr/lib/python2.7/site-packages/cryptography/hazmat/bindings/openssl/binding.py", line 13, in <module>
