Control the output of subcalls to `make`

I have a Makefile where one of the goals looks as follows:

task: $(foreach t,$(SUBDIRS),subtask_$t)

subtask_%:
        make -C $* subtask

In words, task runs the subtask goals defined in each Makefile found in the directories in the list $(SUBDIRS). By default, the output to the console is the combination of all outputs from the subtasks. Is there a way to simply output, e.g. $* SUCCESS or $* FAILED depending on the exit code?

I have tried using @make..., but this doesn't mask the output of the commands run from the other Makefiles.

Ideally, I would like to keep the sub-Makefiles unchanges, as I still occasionally want to use them directly and get the full output.

One possible way would be to get each subtask make write it's output to it's own log file. As in:

subtask_%:
        make -C $* subtask 2>&1 > subtask/make.log
