STD support for PSVita

[nikarh]

This PR adds std support for armv7-sony-vita-newlibeabihf target.

The work here is fairly similar to #95897, just for a different target platform.

This depends on the following pull requests:

rust-lang/backtrace-rs#523
rust-lang/libc#3209

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

• Stabilizing library features
• Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
• Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
• Changing public documentation in ways that create new stability guarantees
• Changing observable runtime behavior of library APIs

These commits modify compiler targets.

Sorry for the force-push spam.

rust-lang/libc#3209 is merged, rust-lang/backtrace-rs#523 is waiting for review.

I would rather wait until libc is released and backtrace-rs is merged, so I'll convert this PR to draft for now.

Now that libc is released, waiting for rust-lang/backtrace-rs#523 to be merged (I assume CI has to be fixed first for rust nightly in its master, but that's out of the scope of my PRs).

After that, I'll update and un-draft this PR.

Does it output as a .vpk file or an eboot.bin? Do you need VitaSDK to use this for Vita?

Does it output as a .vpk file or an eboot.bin? Do you need VitaSDK to use this for Vita?

All relevant doc is here:
https://doc.rust-lang.org/nightly/rustc/platform-support/armv7-sony-vita-newlibeabihf.html

tldr; you can create a static lib in Rust, link it with VitaSDK to an elf, and then do the rest up to vpk with VitaSDK tools.
If you need any help, I suppose it's better to contact me directly, instead of here.
