Feature request: support linux-ppc64le

[jennydaman]

The option --create-executable cannot be used with --platform=linux-ppc64le.

pixi-pack pack --create-executable --platform=linux-ppc64le

I get the following error:

Error: could not archive directory: Unsupported platform: linux-ppc64le

I see that the list of supported platforms are hard-coded:

pixi-pack/src/pack.rs

Lines 369 to 377 in 1ed7234

	let (os, arch) = match platform {
	Platform::Linux64 => ("unknown-linux-musl", "x86_64"),
	Platform::LinuxAarch64 => ("unknown-linux-musl", "aarch64"),
	Platform::Osx64 => ("apple-darwin", "x86_64"),
	Platform::OsxArm64 => ("apple-darwin", "aarch64"),
	Platform::Win64 => ("pc-windows-msvc", "x86_64"),
	Platform::WinArm64 => ("pc-windows-msvc", "aarch64"),
	_ => return Err(anyhow!("Unsupported platform: {}", platform)),
	};

In order to support linux-ppc64le, the code above needs to be modified, and binaries of pixi-pack must be built and published via GitHub releases. Seeing that pixi-pack from conda-forge supports linux-ppc64le, it should be able to build in GitHub Actions for GitHub releases as well.

Could this be implemented? (Would it be helpful for me to draft a PR for this? I can get the code started, but since the issue is related to release engineering, half the work must be done by someone who owns this repo.)

The major thing for this to be implemented is cross-building the executable in CI:

pixi-pack/.github/workflows/build.yml

If we get this to work (which should be possible, see conda-forge), I'm happy to add the binaries 👍

Feel free to open a PR :)
