dev-python/cryptography-3.1.1 fails on compile phase when building against Python 2.7 #69

Hi @stefantalpalaru,

I was doing a regular update on my system and cryptography-3.1.1 fails on compile phase against python 2.7 (which is also built based on your overlay):

>>> Compiling source in /var/tmp/portage/dev-python/cryptography-3.1.1/work/cryptography-3.1.1 ...

Python is compiled with these use flags:

[ebuild   R    ] dev-lang/python-2.7.18-r100:2.7::stefantalpalaru  USE="bluetooth gdbm lto ncurses pgo readline sqlite ssl (threads) (wide-unicode) xml (-berkdb) -build -doc -examples -hardened -ipv6 -libressl -tk -wininst" 0 KiB

Harvesting on the Net, it seems that Python should be compiled with a particular UTF-8 encoding support.

Try rebuilding "dev-python/cffi".

The issue you're hitting seems to be this one: https://github.com/pyca/cryptography/issues/2906

Thank you @stefantalpalaru,

I confirm that rebuilding dev-python/cffi fixed the problem.
