ide-backend fails to build on OSX

[asamiam]

While running the command from stack-ide:

stack install stack-ide stack-ide-api ../ide-backend/ide-backend ../ide-backend/ide-backend-server ../ide-backend/ide-backend-common

on OSX 10.10.4, it fails building ide-backend-server-0.10.0:

The log file says:

I'm still figuring out stack, but I was able to build ide-backend-rts using cabal. Running stack install in ide-backend gave this similar error:

Looks like that message is coming from a homebrew wrapper around gcc: https://github.com/Homebrew/homebrew/blob/master/Library/ENV/4.3/cc#L303

I don't know much about OSX, but if you can make it so that this wrapper isn't used, I imagine it will work.
