Ciro Santilli 六四事件 法轮功 fb396be2cd build-m5: add missing CROSS_COMPILE parameter
The build could fail with:

...
make: arm-linux-gnueabi-ar: Command not found
...

This was working by change previously because I must have had that
installed on all my dev machines. I wonder how it got through Docker
though. Oh well.
