What exactly did you need from ia32-libs? You build-depend on (only libs):
libx11-6, libxext6, libgl1-mesa-glx, libxrandr2, libice6, libsm6,
libfontconfig1, libxi6, libxcursor1, libxinerama-dev
That looks a bit odd to me. I see the source just unpacks the binaries
so I guess you need the libs for the shlibs files. But then why
libxinerama-dev?
Which of those do you actually need in 32bit to build?
>From looking at the package I see that there is fglrx-glx and
fglrx-glx-ia32:
Package: fglrx-glx
Depends: libc6 (>= 2.2.5), libxext6, fglrx-driver (= 1:9-5-1)
Package: fglrx-glx-ia32
Depends: ia32-libs (>= 2.4), lib32gcc1 (>= 1:4.1.1), libc6-i386 (>= 2.2),
fglrx-driver (= 1:9-5-1)
With ia32-apt-get this becomes:
PackagePackage: fglrx-glx-ia32
Depends: ia32-libx11-6, ia32-libxext6, lib32gcc1 (>= 1:4.1.1), fglrx-driver (=
1:9-6-2)
So I guess it is only those 2 libraries you need.
Do me one favour and try this with ia32-apt-get installed:
WARNING: screws with the diversions!
echo 'fglrx-glx +' >>/etc/ia32-libs-tools/rename.list
apt-get update
apt-get remove fglrx-glx-ia32
dpkg-divert --package ia32-fglrx-glx --divert
/usr/lib32/fglrx/diversions/libGL.so.1.2 --rename /usr/lib32/libGL.so.1.2
dpkg-divert --package ia32-fglrx-glx --divert
/usr/lib32/fglrx/diversions/libGL.so.1 --rename /usr/lib32/libGL.so.1
apt-get install ia32-fglrx-glx
Does 32bit GL work with that?
How do you feel about not building fglrx-glx-ia32 on amd64 and
recommending ia32-fglrx-glx instead? It would need a little patch to
the preinst and postrm for the diversion handling. Something like:
if [ "$(dpkg --print-architecture)" = "i386" ]; then
LIBDIR=/usr/lib
PKG=fglrx-glx
else
LIBDIR=/usr/lib32
PKG=ia32-fglrx-glx
fi
dpkg-divert --package $PKG --divert $LIBDIR/fglrx/diversions/libGL.so.1.2
--rename $LIBDIR/libGL.so.1.2
but only in the i386 deb.
Alternatively, not sure yet if that is the right way to go, add a
preinst.amd64 and postrm.amd64 (same for ia64?) file to
DEBIAN/control. ia32-apt-get would then substitude that file when
unpacking the maintainer scripts on amd64.
Or as thrid option I (or fglrx-glx) could include a hook for
ia32-apt-get to rewrite the preinst/postrm scripts on the fly while
unpacking.

It just needs a source for random bits. Without the user as source it
might take longer but buildds must have other sources too. Otherwise
things like ssh or https wouldn't work.

PS: fglrx-glx-ia32 needs to Pre-Depends: libc6 (>= 2.9-18) if you keep it
PPS: ia32-libs has not worked right for buildds making it neccessary
to split out libc6-i386, lib32z1, lib32bz1, lib32asound,
lib32ncurses5, lib32readline5. That Build-Depends was never quite
right.
