From: Linus Torvalds Date: Thu, 19 Mar 2009 22:53:19 +0000 (-0700) Subject: Move cc-option to below arch-specific setup X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d0115552cdb0b4d4146975889fee2e9355515c4b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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."
