You can *run* a 32-bit GHC on a 64-bit Linux install and generate 32-bit
binaries, but it's a bit inconvenient. You usually have to pass the flags
-optc-m32 -optl-m32 -opta-m32
to the 32-bit GHC every time you run it.
We don't support building cross-compilers right now, although much of
the infrastructure is in place and in principle it wouldn't be too hard
to make it work.
Cheers,
Simon

Thanks, That works ok now.
However, the stuff I'd been playing with was mainly inside the code
generator and doesn't seem to work well with the 64 version.
Is there a way I can build the 32 bit version on my machine?
I've tried playing with variations on
./configure --host=x86_64-unknown-linux --target=i386-unknown-linux
--build=i386-unknown-linux
But I get told "cannot run test program while cross compiling".
Sorry, I feel like this is a bit of a stupid question...

It sounds like you need to install an x86_64 build of GHC, either from
your OS's package, or from a bindist from the GHC webpage:
