[PATCH] fix handling of iconv configuration options

[Marco Nelissen <marcone@xs4all.nl>]

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.
