From 33f52ffaf9e603508abb14e7b63cbee48b7eca45 Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Mon, 1 May 2017 11:08:05 -0700 Subject: [PATCH] FROMLIST: efi/libstub: disable LTO With CONFIG_LTO_CLANG, we produce LLVM IR instead of object files. Since LTO is not really needed here and the Makefile assumes we produce an object file, disable LTO for libstub.
