From 105e4b59b7989e9898795273e4064791fdfa056c Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>
Date: Sat, 22 Apr 2017 18:41:50 -0700
Subject: Get rid of config.gen

Instead, prepare the files as a part of bootstrap and install them.
This avoids rebuilding these files in each working directory; they
don't change anyway as they are generated from the same installed
source.
