Yes. I thought we had addressed that during review, but it seems we only
caught one of the two places.

Wei,

I think this bit of stubdom/Makefile:

        ifeq ($(wildcard $(MINI_OS)/Config.mk),)
        $(error Please run `make mini-os-dir' in top-level directory)
        endif

Needs something like this pattern from the end of tools/Rules.mk,
combined with the wildcard stuff (or switching to a dependency on
Config.mk):

        ifeq (,$(findstring clean,$(MAKECMDGOALS)))
        $(XEN_ROOT)/config/Tools.mk:
                $(error You have to run ./configure before building or installing the tools)
        endif
        
I think that'll catch clean and distclean.

Can you whip up a patch please.

Ian.
