Description:
------------
As of PHP 5.2.12, the EXTRA_LDFLAGS line in the Makefile (after running configure) contains the directory pointed to by --with-libxml-dir=/usr/local too late, i.e. after -L/usr/lib, causing the IBM bundled /usr/lib/libxml2.a(libxml2.shr.o) to also be included during linking instead of only /usr/local/lib/libxml2.a(libxml2.so.2).

This despite no changes on the configure line since PHP 5.2.11.

I just wanted to alert you that this may cause problems (unnecessary dependency problems and probably a version collision between the two XML libraries) for those on IBM AIX.

A possible workaround is to specify EXTRA_LDFLAGS=/usr/local/lib ./configure ... so that configure will pick it up and specify it first among the EXTRA_LDFLAGS.

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

'./configure' \
'--enable-bcmath' \
'--enable-calendar' \
'--enable-cli' \
'--enable-dba' \

bwiberg@melody-lp04:~$ /usr/local/bin/xml2-config --libs
-L/usr/local/lib -lxml2 -lz -lpthread -liconv -lm


Expected result:
----------------
No change in EXTRA_LDFLAGS between the versions.

Actual result:
--------------
PHP 5.2.12:

EXTRA_LDFLAGS = -Wl,-brtl -Wl,-bI:$(INSTALL_ROOT)/apache/modules/httpd.exp -avoid-version -module -L/usr/lib -L/usr/local/lib -L/usr/local/lib -L/opt/freeware/lib -L/opt/freeware/lib -L/usr/X11R6/lib -L/usr/X11R6
/lib -L/usr/local/mysql/lib -L/usr/local/mysql/lib -L/usr/local/lib -L/opt/freeware/lib -L/usr/X11R6/lib -L/usr/local/mysql/lib

(Notice -L/usr/lib popping up before -L/usr/local/lib. Also notice the X11R6 and MySQL stuff popping up here.)


PHP 5.2.11:

EXTRA_LDFLAGS = -Wl,-brtl -Wl,-bI:$(INSTALL_ROOT)/apache/modules/httpd.exp -avoid-version -module -L/usr/local/lib -L/opt/freeware/lib -L/usr/X11R6/lib -L/usr/local/mysql/lib
