 Tried to build a few unregisterised targets today. All fail the same as
 x86_64 unregisterised:

 Looks like this code needs an update against '''srt''' / '''has_srt''' (or
 it's another case of leaking build GHC headers into host ghc?):

 {{{#!hs
 peekItbl :: Ptr StgInfoTable -> IO StgInfoTable
 peekItbl a0 = do
 #if defined(TABLES_NEXT_TO_CODE)
   let entry' = Nothing
 #else
   entry' <- Just <$> (#peek StgInfoTable, entry) a0
 #endif
   ptrs' <- (#peek StgInfoTable, layout.payload.ptrs) a0
   nptrs' <- (#peek StgInfoTable, layout.payload.nptrs) a0
   tipe' <- (#peek StgInfoTable, type) a0
 #if __GLASGOW_HASKELL__ > 804
   srtlen' <- (#peek StgInfoTable, srt) a0
 #else
   srtlen' <- (#peek StgInfoTable, srt_bitmap) a0
 #endif
   return StgInfoTable
     { entry  = entry'
     , ptrs   = ptrs'
     , nptrs  = nptrs'
     , tipe   = tipe'
     , srtlen = srtlen'
     , code   = Nothing
     }
 }}}
