Sadly this will also disable all builtin functions (in particular things
like builtin memcpy) unless we take steps to prevent this by adding
-fbuiltin *after* -ffreestanding.
unfortunately, we *don't* want the builtin `printf' because it's wrong.
these builtins should really have their own -fswitches each. :-(
