Thanks for the answer.
And the optimization parameters, I propably will play with them at some time.
https://dev.openwrt.org/changeset/34427
disables sstrip when musl is used,
but does not select strip instead.
Unfortunately I don't know why sstrip got disabled.
But after enabling strip instead the size reaches comparable values (same too a bit larger most of the time).
