## Description:

This update for rust, rust1.77 fixes the following issues:

Changes in rust1.77:

  * update gcc minimum to 13 for SLE (bsc#1222047)

# Version 1.77.0 (2024-03-21)

## Language

  * Reveal opaque types within the defining body for exhaustiveness checking.
  * Stabilize C-string literals.
  * Stabilize THIR unsafeck.
  * Add lint `static_mut_refs` to warn on references to mutable statics.
  * Support async recursive calls (as long as they have indirection).
  * Undeprecate lint `unstable_features` and make use of it in the compiler.
  * Make inductive cycles in coherence ambiguous always.
  * Get rid of type-driven traversal in const-eval interning only as a [future
    compatiblity lint
  * Deny braced macro invocations in let-else.

## Compiler

  * Include lint `soft_unstable` in future breakage reports.
  * Make `i128` and `u128` 16-byte aligned on x86-based targets.
  * Use `--verbose` in diagnostic output.
  * Improve spacing between printed tokens.
  * Merge the `unused_tuple_struct_fields` lint into `dead_code`.
  * Error on incorrect implied bounds in well-formedness check with a temporary
    exception for Bevy.
  * Fix coverage instrumentation/reports for non-ASCII source code.
  * Fix `fn`/`const` items implied bounds and well-formedness check.
  * Promote `riscv32{im|imafc}-unknown-none-elf` targets to tier 2.

## Libraries

  * Implement `From<&[T; N]>` for `Cow<[T]>`.
  * Remove special-case handling of `vec.split_off(0)`.
