Description:
------------
When compiling on AIX, one gets a TOC overflow error from ld.

Something like:
  export LDFLAGS="-Wl,-bbigtoc" (if using gcc) or
  export LDFLAGS="-bbigtoc" (if using cc/xlC)
...prior to running ./configure (and make) appears to be needed.

This was not the case with PHP 5.2.6.

Reproduce code:
---------------
#! /bin/sh
#
# Created by configure

CC='gcc' \
'./configure' \
'--disable-fileinfo' \
'--enable-bcmath' \
'--enable-calendar' \
'--enable-cli' \
'--enable-dba' \
'--enable-dbase' \
'--enable-debug' \
'--enable-exif' \
'--enable-flatfile' \
'--enable-ftp' \
'--enable-gd-jis-conv' \
'--enable-gd-native-ttf' \
'--enable-inifile' \
'--enable-mbstring' \
'--enable-pcntl' \
'--enable-shmop' \
'--enable-soap' \
'--enable-sockets' \
'--enable-sqlite-utf8' \
'--enable-sysvmsg' \
'--enable-sysvsem' \
'--enable-sysvshm' \
'--enable-wddx' \
'--enable-zip' \
'--enable-zend-multibyte' \
'--prefix=/apache/php' \
'--with-apxs2=/apache/bin/apxs' \
'--with-bz2' \
'--with-cdb' \
'--with-curl' \
'--with-freetype-dir' \
'--with-gd' \
'--with-gdbm' \
'--with-gettext' \
'--with-jpeg-dir' \
'--with-ldap' \
'--with-libxml-dir=/usr/local' \
'--with-mime-magic' \
'--with-mysql=mysqlnd' \
'--with-mysqli=mysqlnd' \
'--with-openssl=/opt/freeware' \
'--with-pdo-mysql=mysqlnd' \
'--with-png-dir' \
'--with-xmlrpc' \
'--with-xpm-dir' \
'--with-xsl' \
'--with-zlib' \
'--with-zlib-dir' \
"$@"

Expected result:
----------------
No TOC overflow error. Successful linking.

Actual result:
