commit 4c7549492b301d7d118379c3e98afc0b364d1935

    Simplify INIT_FILES
    
    This simplifies the INIT_FILES variable.  COMMON_OBS includes
    CONFIG_OBS and SUBDIR_GCC_COMPILE_OBS, so there's no need to reference
    CONFIG_OBS or SUBDIR_GCC_COMPILE_SRCS there.  Once this is done, it it
    clear that duplicates can't occur, so remove the duplicate-removing
    code as well.
