#     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.
#     
#     I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and
#     'flags' have been removed.
#     
#     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.
