build: unbreak configure with python 2.6 
Commit 2b1c01c ("build: refactor pkg-config for shared libraries")
from May 2015 introduced python 2.7-specific code.

It mainly affects people building on old RHEL platforms where the system
python is 2.6.  Seemingly a dying breed because the issue went unnoticed
(or at least unreported) for a whole year.

Fixes: #6711
