[Modular CLI] 'No available targets are compatible with triple "aarch64-unknown-linux" on x86_64 system with Ryzen 9000

[chriselrod]

Issue description

On Arch Linux with a Ryzen 9000 CPU:

$ cat /proc/cpuinfo | head -n5
processor	: 0
vendor_id	: AuthenticAMD
cpu family	: 26
model		: 68
model name	: AMD Ryzen 9 9950X 16-Core Processor

I installed using paru -Syu mojo-git.

However, the modular cli failed to install mojo, with an error message relating to aarch64-unknown-linux.

Steps to reproduce

• Include relevant code snippet that did not work as expected.

$ modular install mojo
modular: error: could not construct host target info: No available targets are compatible with triple "aarch64-unknown-linux"

$ modular host-info
modular: error: could not construct host target info: No available targets are compatible with triple "aarch64-unknown-linux"

These look like they're misidentifying the host as aarch64 instead of x86_64.

I don't believe modular currently supports aarch64-unknown-linux, but if it did, perhaps it would have tried to install an incompatible aarch64 binary?

Version Info

- Provide Modular CLI version by pasting the output of `modular -v`

$ modular -v
modular 0.9.2 (b3079bd5)

• What OS did you install modular CLI on ?

$ uname -a
Linux cachy9950xz5 6.10.8-2-cachyos #1 SMP PREEMPT_DYNAMIC Wed, 04 Sep 2024 13:59:35 +0000 x86_64 GNU/Linux

This is an Arch derivative. I was told to file a new issue here: #572 (comment)

Please let me know if there is any other information I can provide.

On another system with the same OS, I get roughly the expected result

$ modular host-info
  Host Information
  ================

  Target Triple: x86_64-unknown-linux
  CPU: tigerlake

CPU and target features are of course expected to differ.

Given that the modular tool is deprecated in favor of magic tool now, I'm going to mark this as "Won't fix".
