if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
vex is amd64-only and there is no point in attempting to build packages
only to have them fail when the RDEP on vex cannot be resolved (e.g. on
i386 as reported by sthen).

angrop is a tool to automatically generate ROP chains.
It is built on top of angr's symbolic execution engine, and uses constraint
solving for generating chains and understanding the effects of gadgets.
angrop should support all the architectures supported by angr, although more
testing needs to be done.
Typically, it can generate rop chains (especially long chains) faster than
humans.
It includes functions to generate chains which are commonly used in exploitation
and CTF's, such as setting registers, and calling functions.
