Fix support Makefile:

- OBJS needs to be declared manually here, because Configure
  does not set it but our `$(OBJS): Makefile' dependency
  line needs OBJS to be defined. If not at least HP/UX make
  complains.

- consistently use $(LDFLAGS) and $(LIBS) even if not
  really needed for rotatelogs

- move TARGETS define in front of the targets itsself
  because some Make variants don't like defines in the
  middle of the targets section
