    kbuild: prefix $(srctree)/ to some included Makefiles · 3204a7fb

    VPATH is used in Kbuild to make pattern rules search for prerequisites
    in both $(objtree) and $(srctree). Some of *.c, *.S files are not real
    sources, but generated by tools such as flex, bison, perl.
    
    In contrast, I doubt the benefit of --include-dir=$(abs_srctree) because
    it is always clear which Makefiles are real sources, and which are not.
    
    So, my hope is to add $(srctree)/ prefix to all check-in Makefiles,
    then remove --include-dir=$(abs_srctree) flag in the future.
    
    I am touching only some Kbuild core parts for now. Treewide fixes will
    be needed to achieve this goal.
