VLS info

Unable to build

Problem Description

Hey folks. I'm trying to run v on my phone so as to have a compact travel setup, primary focus is on exercism solving and scripting.
At the moment I'm able to build v and it runs.
When running v ls --install i get an error as there is no prebuilt variant available

v ls --install
> Finding prebuilt executables from GitHub release..
> Updating VLS repo...
> VLS was already updated to it's latest version.
v ls error: No executable found for this system. (100)

This is expected as the current build only supports x86, mac and windows, but no termux aarch64.

I tried to then build from source

Expected Output

Vls installed || vls built

Actual Output

and it gives me a lot of errors. Too many to print here. The following are just a few lines from a 17k dump

Failed building VLS

Steps to Reproduce

Install termux from the play store (fdroid version leads to my phone crashing in an endless loop, had to factory reset)
Install clang apt install clang
Clone and build v (I'm sure that part is known here)
Run v ls --install
OR
Clone vls
Run v run build.vsh clang

There's a very large Warning in the README for vls that says to use v-analyzer instead.

Please try it, and if you still have a problem, open an issue in that other repo.
