  LoongArch is going to be the first architecture supported by Linux that
has neither fstat* nor newfstatat [1], instead exclusively relying on
statx. So in fstatat64's implementation, we need to also enable statx
usage if neither fstatat64 nor newfstatat is present, to prepare for
this new case of kernel ABI.

v2: add R-b tag

P.S. I don't have commit access so I need someone else to commit this for
me. Also this would need to get in before the LoongArch port, otherwise
it will fail to build here.
