PHP 7.1.2 cannot Gmake : Zend Error

I use Solaris 11.3 Sparc 64 bit, Mysql Enterprise Advance 5.7.1, Apache 2.4.25 and PHP 7.1.2 I configure PHP with following parameter. export CC="gcc -m64" export CFLAGS="-std=gnu99" ./configure --prefix=/opt/app/php --with-openssl=/opt/app/openssl --datadir=/opt/app/php --enable-fpm --with-fpm-user=apache --with-fpm-group=apache --with-pcre-regex=/opt/app/pcre --with-apxs2=/opt/app/apache/bin/apxs --with-mysqli=/opt/app/mysql/mysql/bin/mysql_config --with-mysql-sock=/opt/app/mysql/mysql/socket/mysql.sock --with-libxml-dir=/opt/app/libxml2 --with-bz2 --with-zlib I got the following error. ld: warning: file /usr/gcc/4.8/lib/gcc/sparc-sun-solaris2.11/4.8.2/libgcc.a(_clzdi2.o): wrong ELF class: ELFCLASS32 Undefined first referenced symbol in file __clzdi2 Zend/.libs/zend_alloc.o (symbol belongs to implicit dependency /opt/app/mysql/mysql/lib/libgcc_s.so.1) __ctzdi2 Zend/.libs/zend_alloc.o (symbol belongs to implicit dependency /opt/app/mysql/mysql/lib/libgcc_s.so.1) ld: fatal: symbol referencing errors collect2: error: ld returned 1 exit status gmake: *** [sapi/cli/php] Error 1 From google.com , I found similar problem as me. Bug #71006 Zend: symbol referencing errors. However, I checked at php.net and found out this problem already patched on Version 7.0.1. How should I proceed? Please advice.
