Fix compilation of iconv tests on the Hurd

[Mark Kettenis]

I need the attached patch to compile some of the iconv tests on the
Hurd.  Looks like we get wchar_t from <stdio.h> when we're using
libio.  Is that alright?  I've looked at the ISO C 99 draft, and the
copy I've got here doesn't list wchar_t as defined by <stdio.h>.
