kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED
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.
