Normally I do the following:

rm -rf obj-sparc32
./config/scripts/switch-arch cross-sparc32
(edit obj-sparc32/Makefile to add -O0 -g)
make
cp obj-sparc32/openbios-builtin.elf.nostrip 
path/to/qemu/share/openbios-sparc32

Then fire up qemu with -s -S, connect with "target remote :1234" and set 
the symbols with "symbol-file openbios-builtin.elf.nostrip". Finally set 
everything back in motion with "cont".

Excellent :)
