交叉编译器安装不正确，按照手册重新安装，安装完source一下

我重新安装了天嵌开发包的环境，并且重新拷贝了交叉编译器，确认了能够在系统位置找到 arm-linux-gcc，但是编译还是报错。
请帮我看看还可能是什么问题。

我重新安装了天嵌开发包的环境，并且重新拷贝了交叉编译器，确认了能够在系统位置找到 arm-linux-gcc，但是 ...

把如下命令写成脚本，然后执行脚本编译：
export ARCH=arm
export CROSS_COMPILE=/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/arm-none-linux-gnueabi-
make mx6q_sabresd_android_config
make -j$CPU_JOB_NUM
注意：export CROSS_COMPILE=后面的路径以你实际安装的交叉编译器路径为准

没有生成u-boot.bin，有u-boot.map和u-boot.lds文件，这是什么原因
