I'd rather not go that direction (that is, to using a configure test).
It assumes that all copies of libc on a particular platform behave the
same, which seems like a bad bet to me. I think we'd be better off to
avoid asking libc to do anything that might not work everywhere.
On the other hand, this line of thought might end up having you
reimplement in formatting.c the same logic I put into snprintf.c
recently, which seems a bit silly.
