I'm not sure why you want to change flags in a rule. Perhaps an example 
would help. The only way to do this is to rerun make inside the rule, 
like this:

myrule:
        $(MAKE) ADDITIONAL_OBJCFLAGS=-Wall some_subrule

but that would probably make the Makefile unnecessarily complicated and 
there's probably a better way to do it.
