From 13dc8c029cabf52ba95f60c56eb104d4d95d5889 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 21 Sep 2019 15:49:54 +0900 Subject: kbuild: remove ar-option and KBUILD_ARFLAGS Commit 40df759e2b9e ("kbuild: Fix build with binutils <= 2.19") introduced ar-option and KBUILD_ARFLAGS to deal with old binutils. According to Documentation/process/changes.rst, the current minimal supported version of binutils is 2.21 so you can assume the 'D' option is always supported. Not only GNU ar but also llvm-ar supports it. With the 'D' option hard-coded, there is no more user of ar-option or KBUILD_ARFLAGS.
