Even if we were to resolve the missing types, the PPC64 kernel does not define
a "struct __old_kernel_stat", because it never had one. What is libsanitizer
even doing with the __old_kernel_stat? We switched away from the old kernel
stat ages ago, so I can't believe we're trying to support running on the
ancient kernels.
