[Pkg-rust-maintainers] Bug#946616: dh_auto_install should honor --destdir

[Paride Legovini]

Package: dh-cargo
Version: 21
Severity: normal

After trying to use `dh_auto_install --destdir` as documented in
dh_auto_install(1) I noticed that the option doesn't produce any effect.
I had a quick look at [1] and it seems that the option is currently
being ignored.

When packaging "binary" crates (= not libraries) it is sometimes very
useful to have the files installed in debian/tmp instead of to
debian/pkgname, as this allows more freedom to choose how to actually
install the files in the Debian package using e.g. dh_install and dh-exec.
