Yes.  When GNU make receives a SIGTERM it will catch it, then send a
SIGTERM to each of its children, then die.

SIGTERM.

Also note that users pressing ^C generate a SIGINT, and following normal
UNIX conventions that signal will be passed to all processes in the
process group (make doesn't do anything about this; this is standard
UNIX behavior).
