Subject: Remove unhelpful build warnings

-Wno-writable-strings removes 230 "ISO C++11 does not allow conversion from
string literal to 'char *'" warnings from TensorFlow test / build output.
These happen because pyext/ sources pass string literals to Python C API data
structures, e.g. PyGetSetDef, which for some reason were designed to not have
the const qualifier.
