It still makes sense to pass these sdk flags, if one wants to produce 
portable binaries.

Only linking fails on MacOS 10.5, but a binary linked on MacOS 10.6 
(using ghc-7.0.2 with its sdk flags for 10.5) will run under MacOS 10.5 
as ghc-7.0.2 itself does to a large extend. (I assume ghc-7.0.2 was 
built on MacOS 10.6).
