Did anything change since:

281dc5c5ec0f ("Give up on pushing CC_OPTIMIZE_FOR_SIZE")
3a55fb0d9fe8 ("Tell the world we gave up on pushing CC_OPTIMIZE_FOR_SIZE")

wrt -Os?

Because if not, we still don't love -Os and you can drop the -Os argument.

And without any perf data showing any improvement, this patch does nothing but
enlarge -O2 size...
