If you change the makefile to simply run the command and print the
output, instead of trying to execute it, you'll see the problem.
By default when make recurses it prints a note about this to stdout so
the user knows that a new makefile has been invoked:
make bar
make[1]: Entering directory '/tmp'
echo bar
make[1]: Leaving directory '/tmp'
If you want to avoid these messages, you need to use the
--no-print-directory option; write your makefile with:
foo:
$$($(MAKE) --no-print-directory bar)
bar:
@echo "echo bar"
(you should always use $(MAKE), never just make, when invoking make
recursively).
