Multiarch tests are written in C and need support for printing characters. Instead of implementing the runtime from scratch, just reuse the pc-bios/s390-ccw one. Run tests with -nographic in order to enable SCLP (enable this for the existing tests as well, since it does not hurt). Use the default linker script for the new tests.
