Log: setup.py: use pkg-config for libffi include dir
Some Linux distros don't install ffi.h in the default header search
path. This patch tries to use pkg-config(1) to find the correct
include dir and does nothing if either pkg-config or libffi.pc isn't
available. Distros that need this include Fedora, Red Hat and
apparently Archlinux. Should fix cffi bitbucket issue#2.
Tested on Fedora 17, Ubuntu 10.04 and Ubuntu 12.04.
