Hi Leo,
I reverted the commit in response to this request from Andreas:
http://lists.gnu.org/archive/html/guix-devel/2016-07/msg00011.html

IC. (I would not even have recognised if you'd CC me, since neither the subject nor the content strikes me.)

So we have a dilemma now: not adding `python-config` (at al.) to the wrapper will make packaging more complicated for those Python packages not caring about python resp. python3 in their Makeifles (or what ever they use). OTOH, as these problems with cflags show, this may not work anyway.

I *may* have a look into it, but this will not happen any-time soon.
