PATCH: protect more uses of iconv

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

I have been looking at getting libjava working on *-*-freebsd* again.
We don't define HAVE_ICONV.  It appears some uses of iconv were
unprotected.  Based upon the calling protocol, it appears that doing
nothing is OK in this case.

	* gnu/gcj/convert/natIconv.cc (done): Use HAVE_ICONV.
