Use `rust-lld` instead of `avr-gcc` as the linker

This fixes the [build error] caused by the `avr-gcc` (used as linker)
not being available in the Rust CI. This is a viable solution, which
shows the wrong/right behavior and, since no functions from `libgcc` are
called, does not produce errors. This was discussed [here]. Another
small problem is, that `lld` doesn't link the correct startup-code by
default. This is not a problem for this test (since it does not actually
use anything the startup code is needed for (no variables, no stack, no
interrupts)), but this causes the `main`-function to be removed by the
default flag `--gc-sections`. Therefore the `rmake`-driver also adds the
linker flag `--entry=main` to mark the `main`-function as the entry
point and thus preventing it from getting removed. The code would work
on a real AVR device.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).

Quick Start
