You still should be able to build sparc32 binaries on sparc64 by
performing the build in an environment with sparc32 personality.
Basically, you need to prepend whatever build command you are using
with 'sparc32' (this binary comes from sparc-utils package). That's
how Debian buildds operate.
On a related note, Debian has currently announced that sparc32 is not
going to be supported in lenny. As a side effect, the gcc default
flags are going to be changed to generate code optimized for
ultrasparc processors. I don't know whether sparc32 trick will
continue to work after that, you might need to set your compiler flags
explicitly to avoid generating code which will not run on sparc32.
