    kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED · e91df49f
    Masahiro Yamada authored
    Many (but not all) of Blackfin boards give -O2 option
    to compile under lib/ directory.
    That means lib/ should be speed-optimized,
    whereas other parts should be size-optimized.
    
    We want to keep the same behavior,
    but do not want to parse board/*/config.mk again and again.
    We've got no choice but to invent a new method.
    
    CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled,
    gives -O2 flag only for building under lib/ directory.
    
    Dirty codes which I had marked as "FIX ME"
    in board/${BOARD}/config.mk have been deleted.
    Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been
    defined in include/configs/${BOARD}.h.
