Linux/AM1808: Need help to cross compile qt 5.9 for our current arm tool chain

Tool/software: Linux

Hello,

I have a hardware that runs on AM1808 with Linux installed as os. For the development, I use QT creator to build an GUI based application that uses the qt 4.7.4 compiler along with ARM toolchain to build an app and installed it on this processor. The processor runs on ARM Linux Kernel 2.6.37 that uses toolchain arm2012.03 with gcc version 4.6.3

Now, I need to update the compiler version of qt that is qt 5.7 or above with the ssame toolchain. Here is the download link from where I get this...

http://download.qt.io/official_releases/qt/5.7/5.7.1/single/qt-everywhere-opensource-src-5.7.1.tar.gz

I successfully download it and now need to configure it according to my current toolchain. For that, I update qmake.cong as below,

#
# qmake configuration for building with arm-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

// modifications to g++.conf

//QMAKE_CC                = arm-linux-gnueabi-gcc

//QMAKE_CXX               = arm-linux-gnueabi-g++

//QMAKE_LINK              = arm-linux-gnueabi-g++

//QMAKE_LINK_SHLIB        = arm-linux-gnueabi-g++

// modifications to linux.conf

//QMAKE_AR                = arm-linux-gnueabi-ar cqs

//QMAKE_OBJCOPY           = arm-linux-gnueabi-objcopy

//QMAKE_NM                = arm-linux-gnueabi-nm -P

//QMAKE_STRIP             = arm-linux-gnueabi-strip

QMAKE_CC                = arm-none-linux-gnueabi-gcc

QMAKE_CXX               = arm-none-linux-gnueabi-g++

QMAKE_LINK              = arm-none-linux-gnueabi-g++

QMAKE_LINK_SHLIB        = arm-none-linux-gnueabi-g++

QMAKE_AR                = arm-none-linux-gnueabi-ar cqs

QMAKE_OBJCOPY           = arm-none-linux-gnueabi-objcopy

QMAKE_STRIP             = arm-none-linux-gnueabi-strip

load(qt_config)


To compile this version i use 
./configure -opensource -confirm-license -prefix /usr/local/Qt5 -no-pch -xplatform linux-arm-gnueabi-g++

This is according to our current toolchain and available gcc version. The same like command I used during my old qt installation.

but we found the following error,

Please apply the patch corresponding to your Standard Library vendor, found in /opt/qt-everywhere-opensource-src-5.7.1/qtbase/config.tests/common/atomicfptr

So, this is what I found. Can anyone suggest me a way to resolve this issue?
