Subject: [PATCH] iconv: restore verbosity with unrecognized encoding names
 (bug 30694)

Commit 91927b7c76 ("Rewrite iconv option parsing [BZ #19519]") changed the
iconv program to call __gconv_open directly instead of the iconv_open
wrapper, but the former does not set errno.  Update the caller to
interpret the return codes like iconv_open does.
