Support for ppc64el/ppc64le platforms in Linux

What variant of Codex are you using?

CLI

What feature would you like to see?

Hi team!

It would be great if the Codex CLI supported the ppc64le architecture (sometimes called ppc64el depending on distro, but uniformly powerpc64le-unknown-linux-gnu in rust land). This is a Tier 2 rust target that shouldn't generally have any particular issues compiling. There are quite a number of these systems out there, especially amongst developers who don't like to compromise on "free software/firmware only" (mostly using Raptor Computing's POWER9 platforms), and the platform itself is still widely supported by IBM across many industries.

Additional information

Given that #6150 hasn't resulted in a riscv64 binary being available yet, I don't really expect this to actually happen, but it'd be nice if it did. Would be happy to just build it myself, but it seems the current build process expects a prebuilt version of rusty_v8 to be available, and if there's a build-from-source/exclude-this-feature option to not require that, I've not found it 🥲
