From b34b8b1ffab687116806638c2c8e2bbf0b70d52e Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Mon, 1 May 2017 11:08:05 -0700 Subject: [PATCH 16/24] efi/libstub: disable LTO With CONFIG_LTO_CLANG, we produce LLVM bitcode instead of ELF object files. Since LTO is not really needed here and the Makefile assumes we produce an object file, disable LTO for libstub.
