transform libiconv.dll.a to -liconv for mkoctfile (bug #53920)

* configure.ac (MKOCTFILE_GNULIB_DEPS): Use $MKOCTFILE_LIBICONV
instead of $LIBICONV.
(MKOCTFILE_LIBICONV): New temporary variable.  On mingw systems,
define by transforming libiconv.dll.a to -liconv in the LIBICONV
variable defined by gnulib.
