Subject: testrun.sh: Implement --tool=strace, --tool=valgrind
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

$(file …) appears to be the only convenient way to create files
with newlines and make substitution variables.  This needs make 4.0
(released in 2013), so update the requirement to match.
