No, I never built ghc myself. I downloaded binary packages from
http://www.haskell.org/ghc/

Also, I didn't try to build any package yet, including boot packages,
as I yet have to learn how to make cabal pass -m32 flag to gcc.

The most puzzling thing for me now is whether I can use some technique
to make cabal pass -m32 flag to gcc for every dependency when building
an entire hierarchy of packages, e.g. when cabal-installing yesod.
