Solution

The code is as follows:

Wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
Tar-zxvf libiconv-1.13.1.tar.gz
Cd libiconv-1.13.1
./Configure -- prefix =/usr/local/libiconv
Make
Make install

Check php again

The code is as follows:

#. /Configure -- with-mysql =/backup/mysql -- with-freetype-dir -- with-jpeg-dir -- with-png-dir -- with-zlib -- with-curl --- gd -- enable-gd-native-ttf -- with-apxs2 =/usr/local/apache/bin/apxs -- enable-sockets -- with-iconv =/usr/local/libiconv
# Make
# Make install

Another solution is to remove the iconv module and compile php normally, as shown below:
Too many Makefile is about 77 rows long:
EXTRA_LIBS =...-lcrypt
Add-liconv at the end, for example:
EXTRA_LIBS =...-lcrypt-liconv
Run make again.
