gnumake clobber/clean need fixing (java_hprof_demo) and in general

Top level should just rm the OUTPUTDIR directory.

The INCREMENTAL_BUILD should be set to false on all clean/clobber targets.
It also appears that in general, the SUBDIRS should be traversed in reverse for clean and clobber targets.

This problem was reported for java_hprof_demo too:
Hi Kelly,

I think there's a problem in the Makefile at:
{mustang ws}/j2se/make/java/java_hprof_demo

When I cd into the above directory and do a "gnumake clobber", it fails
indicating the "lint.clean" target isn't defined.

I also saw the same error when I did a "gnumake clobber" from j2se/make
directory.

The error went away after I've made the following changes:
bash-2.05$ sccs diffs -C Makefile

------- Makefile -------
*** /tmp/sccs.Ojaibp Wed Mar 23 12:07:43 2005
--- Makefile Wed Mar 23 11:57:16 2005

*** 136,141 ****

  everything: all linterrs test doc

! clean clobber:: lint.clean
        $(RM) $(LIBDIR)/jvm.hprof.txt

--- 136,141 ----

  everything: all linterrs test doc

! clean clobber::
        $(RM) $(LIBDIR)/jvm.hprof.txt

thanks,
Calvin
