Please provide an actual working example that shows your problem.  This
makefile is malformed and has lots of missing variable assignments, etc.

I tried to condense it down into a reproducible test case but it worked
for me both with GNU make 3.81 and the latest make:

  $ cat Makefile

  SUBDIRS := a b c

  .PHONY: $(SUBDIRS)
  c : a b
  $(SUBDIRS):
        @echo "=> Working on '$@'..."
        +cd $@ && sleep 2

  $ mkdir -p a b c

  $ make-3.81 -j3 c
  => Working on 'a'...
  => Working on 'b'...
  cd a && sleep 2
  cd b && sleep 2
  => Working on 'c'...
  cd c && sleep 2
