The expansion of the value being assigned is not deferred, because the
assignment was done using ":=".  So, the value will be the current
value of local_objs at that point in the makefile.  What is deferred
is the 'availability' of the target-specific assignment: it is only
present during the running of the commands for the clean_dir1
target**.

dependency of clean_dir1, of which there are none in this case,
because clean_dir1 has no dependencies.
