From 6419e144924cf91f8f7c78e914247b02e34b2a89 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 5 Aug 2014 15:56:43 +0900 Subject: kbuild: move extra gcc checks to scripts/Makefile.extrawarn This commit was imported from Linux Kernel: commit a86fe353 written by me. W=... provides extra gcc checks. Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories. Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.
