Indeed, my /usr/include/iconv.h (Linux glibc) says
extern size_t iconv (iconv_t __cd, char **__restrict __inbuf,
                     size_t *__restrict __inbytesleft,
                     char **__restrict __outbuf,
                     size_t *__restrict __outbytesleft);

But it should be  already solved, because
in source/texk/xdvik/m4/xdvi-check-iconv.m4 (from 2013) at the end:
#include <iconv.h>
         ]],
         [[extern size_t iconv(iconv_t, char **, size_t *, char**,
size_t*);]])],
      [xdvi_cv_iconv_char_pptr_type='char **'],
      [xdvi_cv_iconv_char_pptr_type='const char **'])])
AC_DEFINE_UNQUOTED([ICONV_CHAR_PPTR_TYPE], [$xdvi_cv_iconv_char_pptr_type],
                   [Define the type of the iconv input string (char ** or
const char **)])
]) # _XDVI_ICONV_CHAR_PPTR_TYPE

so I guess that at some point there is  a misconfiguration .

In source/Work/build.log, in
=== configuring in xdvik
do you see something like this
checking for iconv.h... yes
checking for library containing iconv... none required
checking for iconv input type... char **
?
