r360139 made compiling with NO_HISTORY work. This #define does not remove the fc and bind builtins completely but makes them always write an error message. However, there was also some code in builtins.def and mkbuiltins to remove the fc builtin entirely (but not the bind builtin). The additional build system complication to make this work seems not worth it, so remove that code.
