Verification of this change --------------------------- 1. Remove `#[unix_sigpipe = "sig_dfl"]` 1. Run `./x.py build` 1. Run `./build/aarch64-apple-darwin/stage1/bin/rustdoc --help | false` 1. Observe ICE 1. Add back `#[unix_sigpipe = "sig_dfl"]` 1. Run `./x.py build` 1. Run `./build/aarch64-apple-darwin/stage1/bin/rustdoc --help | false` 1. Observe ICE fixed
