Making this static disallows unit test writers to create their own
variable arg report() wrapper functions. Perhaps to determine whether
or not a skip is in order, e.g.
xyz_report(msg, pass, ...)
{
va_list va;
va_start(va, pass);
if (xyz)
va_report(msg, pass, false, false, va);
else
va_report(msg, false, false, true, va);
va_end(va);
}

While touching this, please change this to $testname, and anything
else in run() that still uses $N instead of its local var name.
