stable dist choked on artifact consolidation

Example.

Reason is multiple files with the same name inside the different source directories; we need to filter them somehow. Particularly the rust-src tarballs and maybe docs? A ls -R should be helpful.

The problem here I think is that rustbuild is not cleaning up the dist directory before running dist.

The collisions are with 1.15.0 on a build of 1.15.1. These are stale binaries just sitting on the mac builders. Only happens with macs because other platforms run in clean containers.

Nightly and beta produce artifacts that are not differentiated by the name, which is why we didn't see it until a stable release.

Hmm, the explanation makes sense! Manually cleaning the dist dirs of the mac builders and re-triggering a packaging step somehow should fix packaging then.

Fixed on master by rust-lang/rust#39622. Fixed on stable by logging into the build slaves and cleaning manually.
