Summary:                    When building with uClibc, configure script
mistakenly assumes iconv is always available
Description: 
I'm building i586 images for Astlinux using gcc and the uClibc libraries,
but I can't build func_iconv.c because there is no <iconv.h> supplied by
uClibc.

Nor is there a way to turn off func_iconv.c.  I've tried "./configure ...
--with-iconv=no ..." but it still gets turned on.

Seems to come down to:

if test "${host_os}" != "linux-gnu" ; then
  AST_EXT_LIB_CHECK([ICONV], [iconv], [iconv_open], [iconv.h])
else
  PBX_ICONV=1
fi

which erroneously assumes that building with gcc on Linux means you have
iconv.h ... it doesn't mean that at all (at least not for uClibc users).

Turning off iconv (a la --with-iconv=no) should also turn off PBX_ICONV.

  Not all versions of gnu-linux use glibc, which contains iconv.  Some
(especially embedded systems) don't have iconv at all.
