Hi!

rustc upgrades are currently stalled a bit by two factors:
- the planned src:rustc and src:cargo merge not being done yet (which
  might take a bit of FTP master review time before hitting the archive,
  once uploaded)
- t64 still breaking LLVM and thus rustc on armel at least

once those are sorted out, I am planning on speed running incremental
updates as fast as my free time, FTP master review and buildd queues
allow ;)

unless some show stopper shows up that makes that particular change
impossible, enabling loong64 support with the update to 1.71 should be
no problem.
