Compiler Specific dub Dependencies

[Jack Stouffer via Digitalmars-d-learn]

Is there any way in dub to specify that a module should only be 
linked and compiled for DMD and not for LDC?

I am using the Economic Modeling containers library, and because 
it uses std.experimental.allocator, it can't be used with LDC 
through dub. I have coded in such a way with static if's that LDC 
will still compile without it, but dub will try to compile it 
anyway because it's in the dependencies JSON dictionary.
