It might, but I'm not sure how to configure GHC to use a preprocessor that is not
also the C compiler. Especially since I can either (a) add a dependency on a newer
clang, or (b) add a dependency on tradcpp, I'd rather go with clang to make the
port behave as similar to Mavericks and Yosemite as possible.
The build currently fails on SL, because the newer clang generates load commands
that aren't supported by the host's cctools, so I might try tradcpp there instead
of adding a dependency on cctools and making sure they are actually being used
over the host ones.
