Comment (by MikolajKonarski):

 I've worked around the gtk problems by replacing ghc with
 {{{
 ghc-7.8.3 -optc-m32 -opta-m32 -optl-m32 $@
 }}}
 and by setting up the following symlinks (installing both i386 and amd64
 versions of gtk dev libs is not supported on my Ubuntu):
 {{{
 sudo ln -s /lib/i386-linux-gnu/libglib-2.0.so.0 /usr/lib/i386-linux-
 gnu/libglib-2.0.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libgobject-2.0.so.0 /usr/lib/i386
 -linux-gnu/libgobject-2.0.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libgio-2.0.so.0 /usr/lib/i386-linux-
 gnu/libgio-2.0.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libcairo.so.2 /usr/lib/i386-linux-
 gnu/libcairo.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libpango-1.0.so.0 /usr/lib/i386-linux-
 gnu/libpango-1.0.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libpangocairo-1.0.so.0 /usr/lib/i386
 -linux-gnu/libpangocairo-1.0.so
 sudo ln -s  /usr/lib/i386-linux-gnu/libgthread-2.0.so.0 /usr/lib/i386

 sudo ln -s  /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-
 gnu/libX11.so
 }}}

 The GTK calls in the generated binary work great and the binary is
 reported as
 {{{
 ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically
 linked (uses shared libs), for GNU/Linux 2.6.24,
 BuildID[sha1]=0x46cf78948f9bad6f6beed815d6c0f71679830324, stripped
 }}}

 However, there is an unrelated problem: whenever compressions is required
 the binary crashes with
 {{{
 user error (Codec.Compression.Zlib: incompatible zlib version)
 }}}
 The ldd utility reports
 {{{
         libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0xf7025000)
 }}}
 recompiling zlib package with zlib1g-dev:i386 or without and with various
 hacky symlinks doesn't help.
