Title: add ld options

Ability to set LDFLAGS for homebrew issue on Mac OS X because by default I got this error:
```
$ autoreconf
$ LDFLAGS=-L/usr/local/lib cabal install

Failed to install network-2.4.1.1
cabal: Error: some packages failed to install:

```

and network.buildinfo contents:
```

ghc-prof-options: -DCALLCONV=ccall

with this patch I can compile network package with LDFLAGS.
