--disable-library-vanilla

Do not build ordinary libraries. This is useful in conjunction
with --enable-library-profiling
to build only profiling libraries, rather than profiling and
ordinary libraries.

Haven't tried it myself. Maybe it works in combination with --enable-shared?

From: http://haskell.org/ghc/docs/7.0.4/html/Cabal/builders.html

The following two trac tickets mention a separate flag,
named --enable-executable-dynamic:

http://hackage.haskell.org/trac/hackage/ticket/600
http://hackage.haskell.org/trac/hackage/ticket/869

If that doesn't work, you can probably pass some argument to ghc with
--with-ghc-option

Cheers,
Ivan
