+Subject: [PATCH] Fix cross-compilation on some systems
+
+Some Linux distributions (e.g. NixOS, where this issue was spotted) don't provide an unprefixed ar when cross-compiling. This PR aims to fix this.
+
+See[NixOS/nixpkgs#67490](https://github.com/NixOS/nixpkgs/pull/67490) for information on where did it start.
