Subject: old-configure: we accidentally used bash features

In at least 2 places, we want to "shift" positional parameters by a
certain amount, or remove all parameters if there are fewer parameters.
bash handled this just fine, but dash vomits upon it. POSIX shell allows
both behaviors, so we have to fix it.

Fix a comparison done with "==" instead of "=".
