[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.
