Sounds like an X Y problem.

What you want is to cross compile using the NDK toolchain. That should get you 95% of the way there (barring tweaking with downstream project flags to work with bionic libc and limited Android user land and other Android idiosyncrasies)

What I really want (or wanted, I should say) is a native toolchain that runs on the Android device, not a cross toolchain that runs elsewhere. NDK isn't that.
