The change was intentional, but has been reverted--for now.

See these Savannah bugs:


For GNU make 4.4 (unless more changes) this will work the way it used
to work in GNU make 4.3, BUT you will get a warning saying that your
recipe didn't create one of the files.

The current intent is that in the next release after GNU make 4.4, the
behavior will be switched back to GNU make 4.3.90.  So you should
probably prepare your makefiles appropriately.
