From bb14062fd485c1eb94e9d49d08f3dbe7d4d4fe1f Mon Sep 17 00:00:00 2001
From: Slava Barinov <v.barinov@samsung.com>
Date: Mon, 20 Mar 2023 10:22:29 +0300
Subject: Switch to gcc-ar, gcc-nm, gcc-ranlib

Switching to Binutils wrappers for ar, nm and ranlib are required for proper
functioning of Link-Time Optimization features. Currently full support of LTO
plugin is not ready in Binutils, so we need to use wrappers to prevent
"undefined reference" errors:
