Binary builder fails on Termux (aarch64-unknown-linux-android)

[freemin7]

Termux is a slim Linux user space for Android. You can install Julia there in the following way:

• Install Termux (free in F-Droid store)
• run pkg update, pkg upgrade, pkg install tar gnupg wget
• wget https://its-pointless.github.io/setup-pointless-repo.sh and run the script
• pkg install julia

Any binary dependency fails:

First off, we don't officially support Android, so you're going to be hitting codepaths that possibly noone else has ever hit. Fun!

You're running a very old version of Julia (v1.1). Is it possible to get a newer version? Have you tried downloading the official Linux aarch64 binaries and seeing if they run?

I raised an issue with the package directory about Julia being out of date. https://github.com/its-pointless/gcc_termux/issues/93 I've tried to run the binary and was not successful. However i have not exhausted my means and will try things again tomorrow.

I'm curious what it says; I'm betting the libc is just completely wrong, and the loader is missing.
