Fair enough, applied.

That's why there is a pointer to where to get an snprintf()
implementation from in src/utils/os.h.. I'm more worried about some
embedded platforms that are used with wpa_supplicant (some of which even
I'm not really aware of). Anyway, if these can fill in snprintf(), I'd
assume they can handle vsnprintf() extensions as well.
