From 3dcc84e37ce7e94e746304ee2a4437251af0ae41 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Thu, 5 Aug 2021 11:18:20 +0100 Subject: libtool: Fix lto option passing for reproducible builds If lto is enabled, we need the prefix-map variables to be passed to the linker. Add these to the list of options libtool passes through.
