No, those derived files will still be generated at make time.  Because we
have the rule:

$(NAME): $(NAME).cm $(shell $(MLTON) -stop f $(NAME).cm)

and src/yacc.lex.sml will be a file listed in mlyacc.cm, then those
derived files will be generated.

My suggested change was simply for the sake of simplicity.  When I make a
change that I know requires generating a new mlton.cm, I want to just type
make mlton.cm without needing to ensure that I've got the front-end files
built.  Since I'm using the cluster for most builds, I can pretty much get
by with pristine sources on my local machine, in which case, I generally
don't have the front-end files built.  So, I just want make mlton.cm to
work without any additional fuss.
