Fixed bug #714

patch to change HAVE_ICONV to HAVE_ICONV_H
There are two separate iconv checks in configure -- one for the header file and
one for the library. include/SDL_stdinc.h uses the library define to see
whether or not it should reference the types defined in the header, which
naturally breaks if the library exists and the header does not.
