From d23dddf86a12c96d9a3d135a567b9716e5b47821 Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Fri, 11 Dec 2020 10:46:28 -0800 Subject: [PATCH] scripts/mod: disable LTO for empty.c With CONFIG_LTO_CLANG, clang generates LLVM IR instead of ELF object files. As empty.o is used for probing target properties, disable LTO for it to produce an object file instead.
