Looks like this used to work for non-android targets, but we're now breaking it
(by removing repack_whitelist param and not adding toolchain filtering to
windows).

I think breaking it is fine since no other platforms use it, but maybe let's add
an:

if (!is_android && enable_resource_whitelist_generation) {
  print("Warning: GN logic for resource whitelists is implemented only for
Android")
}
