From 62376d99bd012887dd64b876f20e317bcd6bf6ee Mon Sep 17 00:00:00 2001 From: Ben Noordhuis Date: Thu, 19 May 2016 12:29:40 +0200 Subject: [PATCH] build: unbreak configure with python 2.6 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 2b1c01c2c ("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.
