I remember asking some Android devs, "How do I install a compiler on Android?" They proceeded to tell me what to download on my laptop. I repeated my question, emphasizing "ON Android". They gave me blank looks. I said, "I want to install a toolchain ON an Android device, and run it there. How do I do that?" They had no idea. I asked, "What if you want to compile something that requires compiling something, then using that something further down the line, like Perl?" Again, no idea. A platform without a native toolchain is a very awkward place to be. I stopped trying to wrap my head around it and stopped playing with Android.

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.

To me it just sounds like you want Termux. It works pretty well for things like gcc, Python, or Perl. For fun, I managed to get a full X environment running, including Intellij! The amazing thing was that it actually ran fairly decently on a Pixel 5, though it did tend to run out of memory with anything more than trivial projects.

  This looks like exactly what I wanted to find! Thank you. I had been soured by the Android platform because I bought a brand new device, mostly because it had a physical keyboard, only to find out that it wouldn't get any new updates, nor could I use Skype on it, nor could I tether with it. Android was supposed to be the "open" platform, but at the time (which, admittedly, was something like ten or so years ago), it wasn't. If I can use Termux to get a modern OpenSSH on to my device, it may get used yet! Thank you :)

    You can indeed use SSH. As client OR server.
