There are examples in my dub.json files. One here: 
https://github.com/eBay/tsv-utils-dlang/blob/master/tsv-sample/dub.json#L24-L28. All the dub.json files in the repo are setup this way. Turns on LTO (thin) for LDC on OS X, not used for other builds. Works in Travis-CI for the combos of os x and linux with ldc and dmd.
