 I'm trying to cross-(compile/build?) ghc for SmartOS (target) from Mac OS
 X (host).

 I used https://gist.github.com/leroux/6680744#file-
 setup_cross_gcc_linux_illumos-sh to build the gcc cross-compiler (where
 target is solaris and host is os x) and
 https://gist.github.com/leroux/6710457 to kickoff the ghc build process.

 Details
 {{{
 ("Build platform","x86_64-apple-darwin")
 ("Host platform","x86_64-apple-darwin")
 ("Target platform","x86_64-sun-solaris2")
 }}}

 I attempted to remedy this issue by replacing all occurrences of
 `offsetof` with `__builtin_offsetof` which was suggested by
 http://web.archiveorange.com/archive/v/j7U5dymASw992FJprhK7, but it didn't
 have any apparent affects.
