From b744b43f79cc758127042e71f9ad7b1afda30f84 Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Tue, 28 Apr 2020 15:14:15 -0700 Subject: kbuild: add CONFIG_LD_IS_LLD Similarly to the CC_IS_CLANG config, add LD_IS_LLD to avoid GNU ld specific logic such as ld-version or ld-ifversion and gain the ability to select potential features that depend on the linker at configuration time such as LTO.
