On OS X, it is always on; I tried the example on 10.7, Xcode 4.3. I had to add
  ln -s /Applications/Xcode.app/Contents/Developer /Developer
as ghc 7.0.4 looks for /Developer/usr/bin/gcc. For some funny reason ghc is at /usr/bin/ghc; since it is not a system distribution, it should be at /usr/local/bin/, which is also in the system path.

On x86-64, there special relative addressing support, so there is no reason having it turned off, but some other good reasons for having on, like the security reason mentioned here:
