-// libplatform does not have strstr() and we don't want to add any new

-// here. Fortunately, as it's only used to look for boot arguments, it does not
-// have to be efficient. We can also assume that the source string is
-// nul-terminated. Eventually, we will move the function to a more central
-// location and use it to replace other uses of strstr().
