rG04262ed78d23: rtld-elf: Add CFI annotation for .rtld_start on RISC-V
Summary

Without this change, unwinders such as LLVM libunwind will attempt to
unwind beyond the start of RTLD and get stuck in an infinite loop or
crash (depending on the current values on the stack).
This fixes an infinite loop in the LLVM libunwind test suite on RISC-V.
