From 5609c5127dcdcb68fbc76958435a2986f095d939 Mon Sep 17 00:00:00 2001 From: Alex Bennée Date: Mon, 21 May 2018 11:35:04 +0100 Subject: tests/docker/Makefile.include: handle empty TARGET_LIST If the user doesn't specify a TARGET_LIST they get the current configuration but with spaces and hilarity ensues. This adds some make magic to turn the TARGET_LIST back into a comma separated list.
