From d424db235434b8356c6b2d9420b846c7ddcc83ea Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Mon, 18 Dec 2023 17:22:44 +0100 Subject: [PATCH] target/riscv/kvm: do not use non-portable strerrorname_np() strerrorname_np is non-portable and breaks building with musl libc. Use strerror(errno) instead, like we do other places.
