如果交叉编译为ARM的话，需要一个QT_ARCH_ARM的宏，

同理mips的宏为QT_ARCH_MIPS,

需要在你编译的时候给配置上。自己有耐心的话就去查查为什么这个宏变成了QT_ARCH_I386了。

我的错误原因是：Makefile里面QMAKE = 选项指定的qmake 路径错误。本来该是/usr/local/Trolltech/QtEmbedded-4.6.3-arm/bin/qmake
由于我在为配置qmake路径前就 make了一次所以导致 QMAKE选项一直是 /usr/bin/qmake。

（我配置好路径也make过了但是不知道为什么新生成的Makefile里面 QMAKE= 选项没有被改过来）

所以rm 删除 Makefile 从新生产就可以了。
