File 0001-Fix-build-error-in-binutils-2.36.patch of Package grub2.27714
From 7801d671905329d28e789082225570fc54fe5784 Mon Sep 17 00:00:00 2001 From: Michael Chang <mchang@suse.com> Date: Fri, 19 Feb 2021 17:40:43 +0800 Subject: [PATCH] Fix build error in binutils 2.36 The build fails in binutils 2.36 [ 520s] cat kernel_syms.lst > syminfo.lst.new [ 520s] /usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld: section .note.gnu.property VMA [0000000000400158,0000000000400187] overlaps section .bss VMA [000000000000f000,000000000041e1af] It is caused by assembler now generates the GNU property notes section by default. Use the assmbler option -mx86-used-note=no to disable the section from being generated to workaround the ensuing linker issue.
