  * alpha: switch handling of 'foreign import wrapper' (FIW) to libffi
  
  I tried to build ghc-6.12.3 and found out FIW part of code
  does not compile anymore. It uses absent functions under #ifdef.
  Instead of fixing it I just switched to libffi. Result built successfully
  and passed 'foreign import wrapper' test I wrote for trac ticket #3516.
  
  I didn't try to build -HEAD yet, but this patch only removes code, so
  it should not make -HEAD worse.

    M ./compiler/typecheck/TcForeign.lhs -30
    M ./mk/config.mk.in -1 +1
