我使用以下方法在我的Ubuntu系统上安装了交叉编译工具：
sudo apt-get install gcc-arm-linux-gnueabi binutils-arm-linux-gnueabi
然后我制作了简单的.c文件，编译好了，但是当gcc运行汇编程序阶段时，由于未知的原因调用'as'命令，而不是适当的'arm-linux-gnueabi-as'命令，结果编译失败以下错误：
arm-linux-gnueabi-gcc -v test.c
Using built-in specs.

正如您所看到的，它失败了，因为它调用错误的命令 - as ，它只知道 x86_64-linux-gnu 目标，并且不识别 armv5t 架构选项 .
如何强制gcc工具链使用正确的跨平台汇编器/链接器来生成二进制文件，而不是'as''ld'等？我的环境中有什么东西导致这种行为吗？
附：在我大学的机器上，安装相同的工具链没有问题，但是他有Ubuntu 16.04，而我的是17.04 ..而GCC执行以下命令为汇编程序：
/usr/lib/gcc-cross/arm-linux-gnueabi/5/../../../../arm-linux-gnueabi/bin/as -v -march = armv5t -mfloat-abi = soft -meabi = 5 -o /tmp/ccXru9b3.o /tmp/ccUwNPuq.s
正如你所看到的，它需要正确的汇编程序，一切正常..但不在我的系统上..
