It was added in ddee45e when SIGPIPE was controlled with an attribute on `fn main()` which meant it could also be combined with `#[rustc_main]`: #[unix_sigpipe = "sig_dfl"] #[rustc_main] fn rustc_main() { It stopped being needed cde0cde when `#[unix_sigpipe = "..."]` was replaced by `-Zon-broken-pipe=...`. And it will not be needed when `-Zon-broken-pipe=...` is replaced by an Externally Implementable Item. Let's remove this test.
