foreign-libraries break with --enable-profiling

When I compile a project with `foreign-library` sections with `--enable-profiling` `ld` complains about impossible relocations when compiling the flib component. I am using Cabal/cabal-install from [master](https://github.com/haskell/cabal/commit/9db9e696ba14640a3da6c0856f9f0034ed6fe083).

The errors look suspiciously simmilar to the ones from the [GHC bug report about Debian/Ubuntu enabling PIE by default](https://ghc.haskell.org/trac/ghc/ticket/12759), not sure if that's actually related. I'm pretty sure my compilers aren't affected by that since I can also reproduce it in jessie, see below.

To reproduce:

```
$ git clone https://gist.github.com/b0c119d866799812fa2c9d367d67e84a.git
$ cd b0c119d866799812fa2c9d367d67e84a
$ cabal new-build --enable-profiling
```

On Debian jessie (using the ghc-7.8.4 bindist):
