It looks like the apparent regressions in my test results are actually the
result of cascading errors from the test harness (Dejagnu is failing to fully
reset state after a test that got an error talking to the board).  So I'm sure
it's unrelated to the options problem or patch.

Martin, thanks a lot for working on this fix!  :-)
