From 995167420797c000bff1f0787ab2390ffa1a9784 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 30 Oct 2018 22:26:34 +0900 Subject: kbuild: remove cc-name variable There is one more user of $(cc-name) in the top Makefile. It is supposed to detect Clang before invoking Kconfig, so it should still be there in the $(shell ...) form. All the other users of $(cc-name) have been replaced with $(CONFIG_CC_IS_CLANG). Hence, scripts/Kbuild.include does not need to define cc-name any more.
