Ha, my r310171, which enabled sscanf() format checking, is already
working, it seems!  I built kernels for both i386 and amd64 without
problems, but you may be using some non-default module or settings which
trigger this warning.

For which arch are you building here, and do you have any particular
build settings which might influence this?
