how to cross-compile qt4 for arm to generate bin/lrelease and lib/libQtDesigner.so

I am cross-compiling qt4.7.4 on my x86 ubuntu 14.04 target to a aarch64 linux board and I succeeded.

However, there is a problem: I cannot find bin/lrelease and lib/libQtDesigner.so and so on.

How can I configure this so I can build them?

my configure is like this: 

export ROOTFS=/aarch64_2
export CROSS_COMPILE=aarch64-unknown-linux-gnueabi
export PKG_CONFIG_PATH=$ROOTFS/usr/local/lib/aarch64-linux-gnu/pkgconfig:$ROOTFS/usr/lib/aarch64-linux-gnu/pkgconfig:$ROOTFS/usr/lib/pkgconfig:$ROOTFS/usr/share/pkgconfig:$ROOTFS/usr/local/lib/pkgconfig:$ROOTFS/usr/local/share/pkgconfig

./configure -release -v  -fast -opensource 
-developer-build -confirm-license 
-nomake examples -nomake demos 
-nomake docs -nomake translations 
-no-openssl  -webkit -no-qt3support 
-no-rpath -phonon -no-opengl 
-dbus -arch aarch64 -xplatform linux-g++-aarch64   -force-pkg-config

and mkspecs/linux-g++-aarch64/qmake.conf is:

MAKEFILE_GENERATOR  = UNIX
TARGET_PLATFORM     = unix
TEMPLATE        = app
CONFIG          += qt warn_on release incremental link_prl         gdb_dwarf_index
QT += core gui
QMAKE_INCREMENTAL_STYLE = sublib


include(../common/g++.conf)
include(../common/linux.conf)


QMAKE_CC = $$(CROSS_COMPILE)-gcc
QMAKE_CXX = aarch64-unknown-linux-gnueabi-g++
QMAKE_LINK = aarch64-unknown-linux-gnueabi-g++
QMAKE_LINK_SHLIB = aarch64-unknown-linux-gnueabi-g++
QMAKE_AR = $$(CROSS_COMPILE)-ar cr
QMAKE_OBJCOPY = $$(CROSS_COMPILE)-objcopy
QMAKE_STRIP = $$(CROSS_COMPILE)-strip

QMAKE_LFLAGS_RELEASE = -Wl,-O2 
QMAKE_INCDIR += $$(ROOTFS)/usr/include
QMAKE_INCDIR += $$(ROOTFS)/usr/include/aarch64-linux-gnu

QMAKE_LIBDIR += $$(ROOTFS)/usr/lib
QMAKE_LIBDIR += $$(ROOTFS)/usr/lib/aarch64-linux-gnu
QMAKE_LIBDIR += $$(ROOTFS)/lib
QMAKE_LIBDIR += $$(ROOTFS)/lib/aarch64-linux-gnu


QMAKE_INCDIR_X11 = $$(ROOTFS)/usr/include
QMAKE_LIBDIR_X11 = $$(ROOTFS)/usr/lib

QMAKE_INCDIR_OPENGL = $$(ROOTFS)/usr/include
QMAKE_LIBDIR_OPENGL = $$(ROOTFS)/usr/lib

#QMAKE_CFLAGS       = -fpermissive
QMAKE_LFLAGS        = -Wl,-rpath-link $$(ROOTFS)/usr/lib -Wl,-rpath-link     $$(ROOTFS)/usr/lib/aarch64-linux-gnu  -Wl,-rpath-link $$(ROOTFS)/lib -Wl,-rpath-link $$(ROOTFS)/lib/aarch64-linux-gnu

At last, I know why. The configure shell has a comment: don't build tools by default when cross-compiling. So if we are cross-compiling and we want to compile the tools, just add -make tools at the command line.
