conditionalized on cross to minimize rebuilds

Please make this sort of thing unconditional on staging after it's merged — unnecessarily conditionally applied patches lead to annoying problems in future — e.g. a patch no longer applying, but not being tested by the person doing the update, or in this case, the list of platforms used in the condition was non-exhaustive, so I just spent a lot of time chasing the same issue for s390.

the fix is also required on powerpc, and the conditional patching omits the fix there
