Fix infinite loop problem that appear on gcc112 linux machine using GNU make 4.0.

  * Never put destination directory in the dependency list, as it gets modified when
    the target file is created and led to infinite recursion.
    We cannot use $(MKDIRTREE) unconditionally as this generates make error
    at least on Windows OS.
    Instead, create an explicit target for $(TEST_OUTPUTDIR), and add a: 
    $(MAKE) $dir
    line on gparmake, createlst and $(MAKEINC) targets explicitly.
