From 685969e0bd732ff92e6626acc0c05f7204aa7ea6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 27 Jun 2020 03:59:13 +0900 Subject: kbuild: remove cc-option test of -ffreestanding Some Makefiles already pass -ffreestanding unconditionally. For example, arch/arm64/lib/Makefile, arch/x86/purgatory/Makefile. No problem report so far about hard-coding this option. So, we can assume all supported compilers know -ffreestanding. I confirmed GCC 4.8 and Clang manuals document this option. Get rid of cc-option from -ffreestanding.
