You'll need a cross-compiling gcc and binutils.

Yes, that's the problem so far.

Binutils-multiarch is not meant to provide a cross-assembler or
linker...it simply provides multiarch-targetted utilities, such as
objdump and nm. To easily produce a cross-assembler/linker, install the
toolchain-source package and read the docs on that. It's VERY easy to
produce a "binutils-sparc" package with that (in fact, I may even have
one somewhere)...should only be a one or two-command process :-) If you
need help with that, let me know as I've done about 10 cross-assemblers so
far (just not uploaded since they're limited-use).
To produce a full cross-compiling toolchain, you'll also probably need the
headers from a sparc copied over onto your Athlon, FYI, before
bootstrapping gcc.
