#     kbuild: remove 'addtree' and 'flags' magic for header search paths
#     
#     The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated
#     and ugly.
#     
#     As I mentioned in [1], Kbuild should stop automatic prefixing of header
#     search path options.
#     
#     Instead, in-kernel Makefiles should explicitly add $(srctree)/ to
#     the search paths in the srctree.
#     
#     Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj)
#     to the header search path for O= building, but never touches extra
#     compiler options from ccflags-y etc.
#     
#     Going forward, in-kernel Makefiles should explicitly specify
#     $(srctree)/ if extra search paths are needed.
#     
#      Example)    ccflags-y += -I $(srctree)/foo/bar
#     
#     You do not have to change external module Makefiles because $(src)
#     is already an absolute path for external modules.
#     
#      Example)    ccflags-y += -I $(src)/foo/bar
