[PATCH] D12466: Fix empty -L Path on OSX hosts

[Martell Malone via cfe-commits]

martell created this revision.
martell added reviewers: rnk, yaron.keren.
martell added a subscriber: cfe-commits.
martell set the repository for this revision to rL LLVM.

Not quite sure if this is the proper way to fix this.
This is currently my work around when working from an OSX host though.

I think I need some feedback from either rnk or yaron on how to fix this.
I assume the path is supposed to be "." and not an empty string as it is on mac.
I can't reproduce this issue on linux or windows also.
