From c46b34f1d484c11c2a0cbd663168c2213175ca5c Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Mon, 24 Nov 2025 16:18:17 +0100 Subject: [PATCH] rust: kbuild: support using libraries in `rustc_procmacro` Proc macros such as `macros` and `pin-init` will need the ability to use libraries such as `syn` (added later) in the `rustc_procmacro` command. Thus add the support for it.
