Build failure with ldc

[lunik1]

I cannot get trash-d to build with ldc2.

Reproduction:

Running

dub build --compiler=ldc2

gives

     Warning /home/corin/code/d/trash-d/dub.json(5:1): versionName: Key is not a valid member of this section. Did you mean: version, versions, versionFilters

Hmm this is the weird cross section where this issue could be caused by Nix, D, Dub, LLD, or Trash-D and it's hard to tell which of them is causing this.
