Fix GNU libiconv detection

By Kalev Lember

The attached patch fixes GNU libiconv detection by adding an additional
libiconv symbol check to autoconf -liconv link test. Right now some
iconv implementations have only iconv* symbols (GNU libc), some have
only libiconv* (GNU libiconv), and some have both defined (Mac OS X's
iconv), so it's necessary to check for both variants.
