From 8a00021b2ab5529640e5acaca30a27cdaca04178 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Wed, 13 Jul 2016 16:10:28 +0200 Subject: Integrate tests into autotools build system Add automake files for the test binaries. If configured to do so, install the test binaries to libexec/mtd-utils and use autoconf to fix the paths in the test scripts.
