Rollup merge of #117966 - lxy19980601:safe_compilation_options, r=Mark-Simulacrum
add safe compilation options Add two options when building rustc : strip and stack protector. If set `strip = true`, `rustc` will be stripped of symbols using `-Cstrip=symbols`. Also can set `stack-protector` and then `rustc` will be compiled with stack protectors.
