Comment:

 It was pointed out to me today that 64 bit OSX has `-fPIC` turned on by
 default, because that's what the platform ABI requires (quite sensibly),
 but GHC disables `-fllvm` automatically as a result.  Hence you can't use
 `-fllvm` on 64-bit OSX at all.

 I expect we're being too conservative here and it would be fine to enable
 `-fllvm`.  As I understand it, `-dynamic` is the real problem, not
 `-fPIC`.  David?
