From 1d3b97c94eb562fa1071abd50b3a4cb4cca7f203 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Sun, 23 Sep 2018 19:15:15 +0200 Subject: [PATCH] Kbuild: add LDFLAGS_STANDALONE Introduce a new Makefile variable for passing LDFLAGS to standalone programs. Currently the variable CONFIG_STANDALONE_LOAD_ADDR is misued on some archs to pass a specific linker script.
