Thanks for the patch. I agree we should skip the version checks, not
only the actual tests. But I wonder whether we want to do that in
xmethods.exp and prettyprinters.exp rather than in the gdb_batch_check
proc. Or maybe like this instead:

I don't think it really makes much difference, I'm just unsure what is
"cleaner" and more consistent with DG conventions and/or the rest of
the gdb-test.exp file.
