Add menu options for C RunTime library
Mainly to support floating point format strings in printf/scanf functions and their variants. Default settings uses Newlib Nano without floating point support (as before). One can add floating point support for Printf only, Scanf only or both, or just use the standard one. Signed-off-by: ppescher <[email protected]>
