Fail if run in POSIX compatability mode

Browse Source 
This is mostly to detect if someone is running the script with "sh
./stack.sh" where sh is the bash-symlink that puts it in POSIX mode
(this can be invoked in other ways, but much less common).

In this case POSIXLY_CORRECT is set; so if we see that, bail out early
before we start hitting syntax errors.
