This is a tracking issue for the -Z no-unique-section-names debugging option which can reduce the size of object files for ELF targets when using the LLVM codegen backend.

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Bump toolchain to nightly-2023-03-10
4839224 
We can almost use `stable`, except for requiring
`-Z no-unique-section-names=yes` to ensure that all symbols are located
in a single `.text` section (the Flipper Zero loader does not support
unique section names).

See rust-lang/rust#90275

What would the requirements be to stabilise this feature?

Now that Rust 1.68.0 has stabilised #66741 (default alloc error handler), this is the last remaining blocker for supporting a stable toolchain in flipperzero-rs.
