re PR bootstrap/47736 (libquadmath build broken with pre-2.10 glibc) 

PR bootstrap/47736
	* configure.ac (HAVE_PRINTF_HOOKS): Test if printf_info struct has
	user field.
	* printf/quadmath-printf.c (quadmath_snprintf): Clear whole info
	field instead of setting individual fields to 0.  Don't set info.user
	to -1.
	* configure: Regenerated.
