From 1b67bcdfd2e2b329c44e446bbf7aa3a41be25449 Mon Sep 17 00:00:00 2001 From: Christoph Muellner Date: Mon, 28 Jun 2021 02:44:46 +0200 Subject: ldconfig-native: Add RISC-V support The current version of ldconfig does not support RISC-V. Let's add a patch, that adds the required constant definitions (from upstream glibc) and the necessary case statements.
