ghc 7.1 says "Use -fvia-C instead" but -fvia-C is gone

Compiling on linux-powerpc with "GhcUnregisterised=YES" I get:

ghc-stage1: panic! (the 'impossible' happened)
  (GHC version 7.1.20110417 for powerpc-unknown-linux):
        This compiler was built without a native code generator
    Use -fvia-C instead

but the -fvia-C option was removed recently.
