I now have a working toolchain based on binutils-current and
gcc-current (3.4).  It uses the Linux ABI and assembly
conventions.  The good news is that it should be relatively
simple to backport the changes to GCC 3.3.1.

The bad news is that the assembly sources need to be updated
to be compatible with the assembler.
