in this case, we want something to indicate whether GNU iconv is
*actually* being used if USE_GNU_ICONV isn't defined - clearly if the
user defines USE_GNU_ICONV, it's being used :-) so another way to
determine this is needed.

I suspect only a handful of packages actually need this (I've not run
into it on FreeBSD 5, which has iconv* in libc), and expecting them
to all pay attention to '--with-iconv=gnu' seems a bit too fragile.
