Update.

	* iconv/gconv_open.c (__gconv_open): Empty codeset name now means using
	the current locale's codeset.
	* iconv/iconv_open.c (iconv_open): Don't strip out everything for
	empty input string.
	* iconv/iconv_prog.c: Pass empty strings as default value for to-
	and from-charset.  Don't determine locale's charset here.

	if libio is used [PR libc/2575].
