Is there some reason that you didn't use the solution that works in
every version of make that has ever been written and instead used a
complex solution that only has a chance of working in the most recent
versions of a single make implementation?

%_struct.h: %_struct.def
ifdef VERBOSE
        CHIPNAME=`echo $* | tr a-z A-Z` ; \
        $(REGCONV) -chipname $$CHIPNAME $< -simout $@
else
        @CHIPNAME=`echo $* | tr a-z A-Z` ; \
        echo Creating regconv header file CHIPNAME=$$CHIPNAME: $(notdir $@) ; \
        $(REGCONV) -chipname $$CHIPNAME $< -simout $@
endif


If the duplication bugs you:

set_chipname = CHIPNAME=`echo $* | tr a-z A-Z`
regconv = $(REGCONV) -chipname $$CHIPNAME $< -simout $@
ifdef VERBOSE
  describe = echo "$(regconv)"
else
  describe = echo "Creating regconv header file CHIPNAME=$$CHIPNAME:
$(notdir $@)"
endif

%_struct.h: %_struct.def
        @${set_chipname}; ${describe}; ${regconv}


(Yeah, it's a bug in make that it crashes on your makefile...but that
makefile just seems like the wrong way to solve your problem.)
