Title:
  [SRU] dh-cargo: backport Rust LTO enablement facility to Noble

Status in dh-cargo package in Ubuntu:
  Fix Released
Status in dh-cargo source package in Noble:
  New

Bug description:
  [ Impact ]

  Rust packages require an additional change in dh-cargo that adds the
  LTO option to the Cargo build tool.

  This SRU bug tracks the dh-cargo changes backported to Noble.

  [ Test Plan ]

  A limited test-rebuild of Rust binary packages could be performed in a
  PPA to validate that this change does not break any existing package.

  [ Where problems could occur ]

  Older Rust compilers might have issues with LLVM ThinLTO due to LLVM bugs.
  This should affect us since we currently use a newer LLVM version.

  [ Other Info ]

  N/A
