Probably none; on most platforms you're actually generating different code
(dynamic libraries require generation of position-independent code). That
said, the PPC ABI uses position-independent code even for static libraries
and I think Apple decided to go that route on Intel as well rather than
change their build system ... but if you do this then linking to other
platform-native libraries may be more difficult. Not a problem for Apple
since they control the ABI, but not something ghc can force on libc or
random libraries someone might want to use FFI with.
