fix logic bug that would not create lmpinstalledpkgs.h when there was none

	@for p in $(PACKAGEUC) $(PACKUSERUC); do info=$$($(SHELL) Package.sh $$p installed); \

             [ -n "$$info" ] && echo "\"$$info\"" | sed -e 's/".*package/"/' >> lmpinstalledpkgs.tmp || :; done

	@echo ';' >> lmpinstalledpkgs.tmp

	@test "`diff --brief lmpinstalledpkgs.tmp lmpinstalledpkgs.h`" != "" && \

	       mv lmpinstalledpkgs.tmp lmpinstalledpkgs.h || rm lmpinstalledpkgs.tmp

	@if [ -f lmpinstalledpkgs.h ]; \

          then test "`diff --brief lmpinstalledpkgs.tmp lmpinstalledpkgs.h`" != "" && \

	        mv lmpinstalledpkgs.tmp lmpinstalledpkgs.h || rm lmpinstalledpkgs.tmp ; \

        else mv lmpinstalledpkgs.tmp lmpinstalledpkgs.h ; fi

	@if [ -f MAKE/MACHINES/Makefile.$@ ]; \

	  then cp MAKE/MACHINES/Makefile.$@ $(objdir)/Makefile; fi

	@if [ -f MAKE/OPTIONS/Makefile.$@ ]; \
