quadmath-printf.c: Also check __GLIBC__ when checking whether workarounds for printf hook handling...

	* printf/quadmath-printf.c: Also check __GLIBC__ when checking
	whether workarounds for printf hook handling should be added.

	* configure.ac: Check for locale.h too.
	(USE_LOCALE_SUPPORT): Remove check.
	(USE_NL_LANGINFO, USE_NL_LANGINFO_WC, USE_LOCALECONV): New checks.
	(USE_I18_NUMBER_H): Check also for _NL_CTYPE_MB_CUR_MAX.
	* printf/printf_fphex.c (__quadmath_printf_fphex): Use nl_langinfo
	or localeconv for narrow version and nl_langinfo if USE_NL_LANGINFO_WC
	for wide version.
	* printf/quadmath-printf.h: Include locale.h if HAVE_LOCALE_H.
	* printf/printf_fp.c (USE_I18N_NUMBER_H): Don't define to 0.
	(__quadmath_printf_fp): Use nl_langinfo or localeconv for narrow
	version and nl_langinfo if USE_NL_LANGINFO_WC for wide version.
	Guard nl_langinfo (_NL_CTYPE_MB_CUR_MAX) use with
	USE_I18N_NUMBER_H #ifdef.
	* configure: Regenerated.
	* config.h.in: Regenerated.
