Title:
  rustc-1.80-src: missing `lib/rustlib/src` in sysroot

Status in rustc-1.80 package in Ubuntu:
  Fix Released

Bug description:
  Hi,

  The following difference between the versioned (`rustc`) and non-
  versioned (`rustc-1.80`) packages means that downstream Rust users may
  need to tweak build steps for a project if the versioned packages are
  used:

      $ dpkg -L rust-src | grep rustlib
      /usr/lib/rustlib
      /usr/lib/rustlib/src
      /usr/lib/rustlib/src/rust

      $ rustc --print sysroot
      /usr

      $ ls -l $(rustc --print sysroot)/lib/rustlib/src
      total 0
      lrwxrwxrwx 1 root root 25 Feb 14  2024 rust -> ../../../src/rustc-1.75.0

  vs.:

      $ dpkg -L rust-1.80-src | grep rustlib
      /usr/lib/rust-1.80/rustlib
      /usr/lib/rust-1.80/rustlib/src
      /usr/lib/rust-1.80/rustlib/src/rust

      $ rustc-1.80 --print sysroot
      /usr/lib/rust-1.80

      $ ls -l $(rustc-1.80 --print sysroot)/lib/rustlib/src
      ls: cannot access '/usr/lib/rust-1.80/lib/rustlib/src': No such file or directory

  Ubuntu's non-versioned package, as well as other distributions, such
  as Debian and Fedora, allow to use that `src` path to find the
  standard library sources, e.g.:

      $(rustc --print
  sysroot)/lib/rustlib/src/rust/library/core/src/lib.rs

  Could the versioned packages (at least future ones) be changed so that
  `src` exists? If so, that would allow to simplify instructions for
  Ubuntu users in e.g. the Linux kernel Quick Start guide for the Rust
  support:

      https://docs.kernel.org/next/rust/quick-start.html#ubuntu

  Thanks!

  Cheers,
  Miguel
