[PATCH] libc/newlib: remove hard-coded "-O"

exporting patch:
# HG changeset patch
# User Zhenqiang Chen <zhenqiang.chen@linaro.org>
# Date 1322467523 -28800
# Node ID 6e30947fabf76287cc92c16a12421aaa7ab51f0c

libc/newlib: remove hard-coded "-O"

With hard-coded "-O", users can not customize CFLAGS_FOR_TARGET
by CT_TARGET_CFLAGS. If "-O" is needed, users can input it in
CT_TARGET_CFLAGS. By default, "-Os" is enabled.
