Since LLVM commit 39e30508a7f6 ("[Driver][Sparc] Default to -mcpu=v9 for 32-bit Linux/sparc64 (#109278)"), clang defaults to -mcpu=v9 for 32-bit SPARC builds. -mcpu=v9 generates instructions which are not recognized by qemu-sparc and qemu-system-sparc. Instead qemu-sparc32plus and qemu-system-sparc64 with a 64-bit kernel and CONFIG_COMPAT are needed.
Rework the test setup so that -mcpu=v9 also works correctly.
