#56708: cargo @0.27.0: failing to destroot

 `cargo` seems to build fine, but then fails to destroot on my 10.9
 machine:

 {{{
 :error:destroot Failed to destroot cargo: xinstall: Cannot stat:
 /opt/local/var/macports/build/_opt_local_var_macports_sources_macports.rsync.ionic.de_release_ports_devel_cargo/cargo/work/cargo-0.27.0/target/x86_64
 -apple-darwin/release/cargo, No such file or directory
 }}}

 This is with `rust` built universally, if that matters. `cargo` fails to
 destroot both `+universal` and `-universal` build configurations.

 Looking through the file tree, the error makes sense, since a `cargo`
 binary seems to be located at `target/release/cargo` - mind the missing
 triplet subdirectory.
