I've checked in this trivial patch to fix another test failure I found
on nios2-elf, due to the BSP we use for simulator testing on this target
not having support for argc/argv. This testcase doesn't actually use
any command-line arguments and I think just does the argc test to avoid
optimizing the interesting things away, so I tweaked it to allow argc ==
0 in addition to argc == 1.
