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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Sonic Zhang <sonic.zhang@analog.com>
