From d0115552cdb0b4d4146975889fee2e9355515c4b Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 19 Mar 2009 15:53:19 -0700 Subject: Move cc-option to below arch-specific setup Sam Ravnborg says: "We have several architectures that plays strange games with $(CC) and $(CROSS_COMPILE). So we need to postpone any use of $(call cc-option..) until we have included the arch specific Makefile so we try with the correct $(CC) version."
