Comment (by MikolajKonarski):

 Here is the trivial workaround (perhaps I should add it to the wiki
 somewhere and then close the ticket?):

 {{{
 CFLAGS=-m32 ./configure --prefix=.....
 }}}

 Now I can compile many packages and the 32bit executables work (e.g.,
 alex, happy). I still struggle with gtk2hs and I haven't tried beasts like
 yesod, etc, though. The command I use is

 {{{
 cabal install --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-
 option="-optl-m32" --ld-option="-melf_i386"
 }}}

 == Long story ==

 The workaround is inspired by https://ghc.haskell.org/trac/ghc/ticket/8910
 and http://www.haskell.org/pipermail/glasgow-haskell-
 users/2012-February/022014.html

 I had to install many -dev:i386 versions of libraries on my Ubuntu to make
 it work. The most problematic was libgmp-dev, since my Ubuntu only
 tolerates amd64 or i386 version of this lib at once (zlib1g-dev:i386
 didn't have that problem). I ended up adding a hacky symlink instead of
 the -dev:i386 version:

 {{{
 sudo ln -s /usr/lib/i386-linux-gnu/libgmp.so.10.0.2 /usr/lib/i386-linux-
 gnu/libgmp.so
 }}}

 == The remaining gtk2hs problem ==

 This is probably a bug in gtk2hs-buildtools (I reinstalled them for 32bits
 with many extra flags, but no improvement), but I won't report it on
 gtk2hs issue tracker until I research a bit more. I try monstrosities like

 {{{
 CFLAGS=-m32 cabal install glib -j1 --ghc-option="-optc-m32" --ghc-
 option="-opta-m32" --ghc-option="-optl-m32" --ld-option="-melf_i386" -v3
 --gcc-option="-m32" --configure-option="CFLAGS=-m32" --ghc-option="-optl-
 Wl,-melf_i386"
 }}}

 but I'm still getting

 I haven't looked inside the generated files nor inside the gtk2hs-
 buildtools yet.
