[PATCH 02/50] Add a simple getarg function.

If we ever need to get more than one kernel command line argument, this function will pay for itself. It relies on a feature of the way bash handles string comparisons in [[ ]] statements -- the RHS is matched according to globbing rules, and is not a straight string match.
