Commit 5b2aaa117eee ("libutee: optimize memcpy() for speed") added -O2
to memset.c to exclude the slower implementation which would be selected
when level is -Os (in which case __OPTIMIZE_SIZE__ is defined).
Since the optimization level can now be selected globally with
CFG_CC_OPT_LEVEL, -O2 should not be forced unconditionally or it could
actually reduce the desired level (when CFG_CC_OPT_LEVEL=3).
Therefore, add -O2 only if the global optimization is -Os.
