[scripts/functions]: Fix quoting issue in comparison

Browse Source 
On my Ubuntu machine (with `dash` version `0.5.10` and `bash` version `5.0.17`),
I would get errors such as the following:

```
crosstool-ng/scripts/functions: line 730: [: !=: unary operator expected
```

This is generally because a variable is not set, and expands to an empty string
causing the test operator to mis-parse the expression.  To fix this, I have
added quotes around the variable.
