pref-llvm failed at integer-gmp-0.3.0.0: stored value and pointer type do not match

The GHC in the trunk (revision [bcb59950]) does not build in the final stage with "pref-llvm":

"inplace/bin/ghc-stage1" -fPIC -dynamic  -O -H64m -fllvm
    -package-name integer-gmp-0.3.0.0 -hide-all-packages
    (...snipped...)
