When I copy the cross-compiled binary to an armhf machine, the 
executable cannot get executed.

```
# ./test 
/lib/ld-linux.so.3: No such file or directory
```

I wonder whether it is a bug or left on purpose.

After looking into the problem deeply, I found that I've used a wrong 
compiler. The right one should be `gcc-arm-linux-gnueabihf`.

Just for reference, there are three architectures: armel, armhf and 
arm64 in Debian package archive about arm, and the corresponding 
compilers should be gcc-arm-linux-gnueabi, gcc-arm-linux-gnueabihf,
and gcc-aarch64-linux-gnu.
