This most likely means that your op.o has a relocation without a proper
symbol name. This can happen if a relocation is split into loword
and hiword on some architectures. What host are you compiling for?

Looking at target-sparc/op.c, I see that op_fitos does not take any
__op_param parameters, but rather just stores env->ft1 into env->ft0. So
maybe those relocations are not necessary. You can try that by hacking
dyngen.c after the "/* patch relocations */" line to just ignore
those without a proper name. YMMV.
