ACK dd85166b6c8200265ff222226305e6823149de19, tested locally on Linux Mint 19.2.

The code on master failed if the absolute path /.../bitcoin/autogen.sh contains many-words directory name, and script runs from out-of-the-tree:
```
ls ~/git\ hub/bitcoin/autogen.sh 
'/home/hebasto/git hub/bitcoin/autogen.sh'

~/git\ hub/bitcoin/autogen.sh 
/home/hebasto/git hub/bitcoin/autogen.sh: 9: cd: can't cd to /home/hebasto
hub/bitcoin
```
With this PR it works as expected.

But our code base contains other the same cases (I mean special parameters $0), so I suggest to be consistent, and fix them all.

The build system has never worked in paths with spaces in it, I hope at some point that can be solved, this is a step in the right direction at least.

@mztriz

Would it be feasible to enable SC2086 rule for ShellCheck linter globally?
