On a machine without the file command, the SDK install fails with a
cryptic error message.
```
xargs: file: No such file or directory
sed: no input files
Failed to replace perl. Relocate script failed. Abort!
```
Add a test for 'file' to print a clear error message.
```
The command 'file' is required by the relocation script, please install it first. Abort!
