Both `clang-s390x-linux` and `clang-s390x-linux-lnt` failed with the same `Clang::bindings.sh` error:

https://lab.llvm.org/buildbot/#/builders/136/builds/4462

The `clang-s390x-linux-multistage` run including this change did indeed pass:
https://lab.llvm.org/buildbot/#/builders/98/builds/1625

The main difference between this and the others is that in the multistage build, the clang that is used to run the test suite was itself built using (the same version of) clang as host compiler, while the other two build clang using the system GCC as host compiler.

It's not immediately obvious to me why the host compiler would make any difference on this particular PR ...
