In commit bbfceba15f8d ("kdb: Get rid of confusing diag msg from "rd"
if current task has no regs") I tried to clean things up by using "if"
instead of "#ifdef". Turns out we really need "#ifdef" since not all
architectures define some of the structures that the code is referring
to.
Let's switch to #ifdef again, but at least avoid using it inside of
the function.

task has no regs")

I don't have a sparc64 compiler but I'm pretty sure this should work.
Testing appreciated.
