After recent jdk25 make changes, make -t now fails with error:
make[1]: *** wait: No child processes. Stop.
make: *** [default] Error 2

If I use GNU make 4.4.1, then the above error does not occur, but I cannot make any images.

To reproduce:
- Build the "default" exploded image: "make"
- Then run: "make -t" => Fails with GNU make 3.8.1, works with GNU make 4.4.1
- Then try an make images, and get:
make: *** No rule to make target `images'. Stop.

It seems related to the processing of "create-main-targets-include"
If I delete this file after "make -t", then "make images" works
