No, I didn't actually try anything. Between trying to test the kcfi
stuff on arm64 and the other work I was doing today I did not have a
chance to actually play with that yet. It comes down to you though I
suppose - would you rather have generate_rust_target enable the
compressed instructions depending on the config option or have the
Makefile disable it if compressed instructions are not enabled and use
a builtin target?
