That's libkern. It's part of the kernel code, and it cannot depend on
the same basic assumptions as /usr/src/lib/libc code.
The kernel version of sprintf() is implemented in sys/kern/subr_prf.c.

This, on the other hand, is userlevel code. There is a userlevel
implementation of the printf() family of functions in libc.
The two versions do not necessarily work in an 100% compatible manner,
so it's probably a slightly bad idea to 'fix' kernel code to use the
libc/userlevel style of sprintf("%u....").
