Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Can I force rust to treat stdlib like other crates in terms of linkage?
I don't know which symbols are missing, haven't done anything on the llvm level. But I had the same problems creating a no-std no-libc application, if you add https://github.com/rust-lang/compiler-builtins as a dependency you should get all the symbols you need, std uses the same but if you want to use it outside of std you'll need nightly since it uses a lot a nightly features. It might apply to your case as well.

rustc + avr = lovelove back again!
I'm glad to inform y'all that after a year, the infamous LLVM ERROR: Not supported instr bug¹ has been finally fixed and today's nightly can compile for AVR back again! 😎

Porting Rust's std to rustix
Then, some of the non-trivial things that are needed are already implemented and maintained in other crates, like memcpy and friends in compiler-builtins, all the math routines in libm and malloc in dlmalloc.

rustc + avr = lovelove back again!
Also note that some libraries in the ecosystem might still use a feature called llvm_asm that was removed from rustc in 2021, so those crates might need a while to migrate to the newer asm syntax (this feature is used to provide an inline AVR assembly, e.g. to implement a cycle-accurate delay); so far I've got patches merged to https://github.com/Rahix/avr-hal & https://github.com/Rahix/avr-device :-)

Rust for microcontrollers question
Take a look at the avr-device crate, it also explains how to add a new controller and how to get to the svd files.
What are some alternatives?
rt-thread - RT-Thread is an open source IoT real-time operating system (RTOS).
avr-hal - embedded-hal abstractions for AVR microcontrollers
wee_alloc - The Wasm-Enabled, Elfin Allocator
rustsbi - RISC-V Supervisor Binary Interface (RISC-V SBI) library in Rust; runs on M or HS mode; good support for embedded Rust ecosystem. For binary download see https://github.com/rustsbi/standalone.
relibc - Mirror of https://gitlab.redox-os.org/redox-os/relibc
