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.Explicitly enforce -mcpu=v8 to generate compatible code.
