From d8672b40d3a6f17de5b5bc71d6e531d7576a856a Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 21 Nov 2008 21:50:02 +0100 Subject: kbuild: expand -I in KBUILD_CPPFLAGS kbuild failed to expand include flags in KBUILD_CPPFLAGS resulting in code like this in arch Makefiles: ifeq ($(KBUILD_SRC),) KBUILD_CPPFLAGS += -Iinclude/foo else KBUILD_CPPFLAGS += -I$(srctree)/include/foo endif Move use of LINUXINCLUDE into Makefile.lib to allow us to expand -I directives of KBUILD_CPPFLAGS so we can avoid the above code.
