linking fails with 'relocation R_X86_64_PC32 against undefined symbol'

Building ekmett's lens package from HEAD (revision 80c1fddf) with the following error fragment:

ExitFailure 1

Full log is attached. I'm not trying to build with shared libraries, or profiling, or anything like that.

I can reproduce this failure starting from a fresh Debian testing install as follows:

1. Bootstrap GHC HEAD.

sudo aptitude install ghc=7.6.3-6 happy=1.19.0-1 alex=3.1.0-1
sudo apt-get build-dep ghc
cd /var/tmp
git clone git://git.haskell.org/ghc.git
cd ghc
git checkout e01367ff
./sync-all get
./boot
./configure
# Adjust the -j option to taste.
make -j4
sudo make install

1. Bootstrap cabal-install.

cd /var/tmp
wget http://www.haskell.org/cabal/release/cabal-install-1.18.0.2/cabal-install-1.18.0.2.tar.gz -O - | tar xzf -
cd cabal-install-1.18.0.2
patch -p3 < cabal-install-ghc-HEAD.patch # see attached
sudo aptitude install zlib1g-dev
./bootstrap.sh
export PATH=$HOME/.cabal/bin:$PATH
cabal update

1. Build lens.

cd /var/tmp
git clone https://github.com/ekmett/lens
cd lens
git checkout 80c1fddf
cabal install cpphs
cabal install # this fails

Using gcc Debian 4.8.2-14, ld 2.24. The GHC fingerprint and output of ghc --info is attached.
