scripting bug: unknown option or argument >/usr/src/libdvd-pkg/libdvdcss2_1.3.99-1~local_amd64.build

[Peter Cordes]

When installing 1.3.99-1-1 on Ubuntu 15.10 (AMD64), I get the following error while the package configures itself:

```

I haven't investigated further, but presumably someone was expecting shell-expansion on that arg.

My /bin/sh is dash.
