Auto merge of #53996 - sekineh:thumb-run, r=japaric
[CI] Run a `thumbv7m-none-eabi` binary using `qemu-system-arm` [IRR-2018-embedded]

## What's included?

- Run a `thumbv7m-none-eabi` binary using `qemu-system-arm`
- We are using `cortex-m-rt = "=0.5.4"` which does not use `proc_macro`.
(reason: stage2 build of rustc does not work well with `proc_macro` in `run-make` phase.)
- We are using GNU LD for now.

## Blocker

All resolved.
- ~[Waiting] `#[panic_handler]` is not available in stable.~
  - [Merged] https://github.com/rust-lang/rust/pull/53619
- ~[Waiting] https://github.com/japaric/lm3s6965evb: does not compile on stable.~
  - [OK] dependent crate ~`panic-abort`~ `panic-halt`: already moved to use `#[panic_handler]`.

## Update

`#[panic_handler]` will be stabilized in Rust 1.30.
