ghc hasn't generated C code for a while, aside from unregisterised.

It's not truly a different architecture, but a reorganization of the
standard architecture. Unfortunately, ghc doesn't currently make good use
of the key Xeon Phi components even in the standard architecture; packages
that want to make use of them generally use -fllvm because LLVM is better
at using them, even given that LLVM isn't very good at understanding what
ghc feeds it. This suggests that -fflvm might be useful in taking advantage
of Xeon Phi architecture with ghc.
