yes thats a gap agreed.

-pipe does speed up build time so its an optimization. FULL_OPTIMIZATION is not
about
code generation only. However, I agree to the fact that if we want to use
it in all combination then it should go into a common global variable which is
common
across target/native/nativesdk recipes.
