Makefile: m4_changequote([[[, ]]]) to avoid accidental quoting.
The default m4 quote characters: `QUOTE' are troublesome, because ` is fairly likely to pop up in a shell script (if not for a subshell, because it is a useful character in comments and user-facing messages). So, this changes it to [[[QUOTE]]], as it is unlikely to see three braces together like that, let alone in unbalanced sets.
