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.

The Firm library implements the Firm intermediate representation (ir).
libFirm contains algorithms for construction of the SSA form directly
from the attributed syntax tree. A set of analyses and optimization
phases is provided.
libFirm includes backends of varying maturities for IA32, AMD64, ARM,
and other architectures.
Features:
* Completely graph-based, source- and target-independent intermediate
representation in SSA form
* Extensive set of optimizations
* High-quality register allocation
