From 388b2e520b07cc857c03a152fc6006763f78b9d6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 5 Mar 2014 17:49:22 +0900 Subject: kbuild: move "checkthumb" to ARM archprepare "checkthumb" makes sense only for ARM architecture. Move it to arch/arm/config.mk. To make sure gcc supports THUMB mode before beginning build, run "checkthumb" during "archprepare".
