Recently I had to look into the code for waf to fix a build issue (see bug
195953 for the gory details). If such a feature is going to be built, maybe
this PR can be taken into account.

What I observed is that python2.7-config is a Python sccript, while
python3.4m-config is a shell-script. And waf assumes the config script is a
Python script.

The version of waf bundled with that port is quite old (1.6.4). The source
code of that version is extremely terse with few if any docstrings and almost
no blank lines. It produces an awesome amount of errors and warnings when you
run it through flake8. The most recent version is a lot better in that regard.
So I wonder if the different versions are compatible enough to make a generic
USE_PYTHON=waf feature possible.
