      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.
