  Log Message:
  -----------
  [hwasan] Replace j __interceptor_sigsetjmp instead with tail for RISC-V

R_RISCV_JAL referencing a preemptible symbol is disallowed with ld.lld and binutils 2.40 (https://sourceware.org/PR28509)

    riscv64-yoe-linux-ld: relocation R_RISCV_JAL against `__interceptor_sigsetjmp' which may bind externally can not be used when making a shared object; recompile with -fPIC
