Remove an item from things-todo.md

I believe that the task of dealing with messages/warnings in the
Makefile about compilation has now been addressed. If this is not the
case it will be fixed in time but I believe it has been done.

-    * Make compilation of targets use `|| :` in the Makefiles to allow
-    additional targets to compile and/or let warnings/notes be printed. An
