From: Ian Jordan <immoloism@gmail.com>
Date: Thu, 01 Nov 204 15:28:39 +0100
Subject: Change Pentium4 baseline to i586
Based on the Debian patch at https://sources.debian.org/patches/rustc/1.80.1%2Bdfsg1-1/behaviour/d-rustc-i686-baseline.patch/
This lowers baseline from Pentium4 to i586.
Thanks-to: Debian Rust Maintainers <pkg-rust-maintainers@alioth-lists.debian.net>
