Fixed: uname option to recognize hardware architecture

`uname -p` gives processor information

```
uname -p
Intel(R) Core(TM) i3-2130 CPU @ 3.40GHz
```

While `uname -m` gives CPU architecture information (bit-ness of CPU)

```
uname -m
x86_64
```

From the context of this statement, `uname -m` should be used here.
