waf raise StopIteration with python 3.7

[patatetom]

hello,

since python3 update (3.6.6-1 -> 3.7.0-3), blockhash no longer build :

python3.7 waf configure

Traceback (most recent call last):
  File "/tmp/blockhash-0.3.1/.waf3-1.7.16-9ca17eb492c97b689870b4ff9db75880/waflib/Node.py", line 282, in ant_iter
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

Hi, @patatetom thanks for the heads up. I've updated waf to version 2.0.10, could you verify that it works with python 3.7? Thx!
