[PATCH 00/12] Rust build system v2.

[David Craven]

Here are my cleaned up rust patches. They aren't too useful yet
IMO. Patches 1-9 could be merged. rust-rand, cargo and the
recursive importer are for reference in case someone wants to play
with it.

  upstream: Use a the first url from urls when find2 returns #f.
  build-system: Add cargo build system.
  import: utils: Add some utilities.
  import: Add importer for rust crates.
  import: Add updater for rust crates.
  gnu: llvm: Enable install utils.
  gnu: Add rust bootstrap binaries.
  gnu: Add rustc.
  gnu: Add rust-libc.
  RECURSIVE IMPORTER wip
  gnu: Add rust-rand.
  gnu: Add cargo.
