Fix the way in which the configure script handles --without-iconv
(and --with-iconv=no), which it  used to essentially ignore.
Also fix the way the configure script determines the value of
NEEDS_LIBICONV, which would be incorrectly set to 'YesPlease' on
systems that lack iconv entirely.

Since configure.ac uses a mix of 2, 3 and 4 space indentation and tabs, I
wasn't quite sure what to do with regard to that. I decided to keep the
number of lines changed to a minimum, rather than changing indentation
for a bunch of lines.

Hmm, have you tested this with both NO_ICONV defined and undefined?

Because ...

	$ test -z ; echo $?
        0
	$ test -n ; echo $?
        0

... I would feel better if you had dq around $NO_ICONV in both tests.

```

Ah, you're right. I tested that it didn't incorrectly set
NEEDS_LIBICONV on a system that doesn't have/need it, but didn't test
that it doesn't unset it on a system that does need it (because I
don't have such a system).
