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.
