 Teach GHCi to use the system runtime linker to load Haskell libraries on
 powerpc64.

 See the following test failures.

 ghcilink004:
 {{{
 ghc-stage2: dir004/libfoo.a: unknown architecture (e_machine == 21)
 ghc-stage2: panic! (the 'impossible' happened)

   error, called at libraries/ghci/GHCi/ObjLink.hs:91:21 in
