Python package build not working in build-python3.6

[mhart]

The Amazon Linux yum repos don't have any devel packages available for Python 3.6

You can install the include libs and files from the Python source:

curl https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz | tar -xJ
cd Python-3.6.1
./configure --prefix=/var/lang
make -j$(getconf _NPROCESSORS_ONLN) libinstall inclinstall

pip3 install cryptography will then succeed

I'm happy to add these lines to the build Dockerfile – I'm just mindful that ppl may get overconfident in assuming certain libraries and headers are available on the python3.6 Lambda when they're actually not.

So I added this to the latest build-python3.6 image – can check progress on the Docker builds here: https://hub.docker.com/r/lambci/lambda/builds/

Let me know if that solves your issue

[mhart]

Build done. Confirmed that docker run lambci/lambda:build-python3.6 pip3 install cryptography works as expected

Looks good, thanks for the quick fix!
