The riscv backend is fairly new. I don't have access to a riscv setup,
so cannot easily check myself. I have CCed Andreas, who wrote the port
and might be able to diagnose what is going on.

The first failure is for the location description of a return value,
which is kind of expected since riscv doesn't have a
return_value_location backend function yet.

The other 3 failures are all for the self-tests doing unwinding and
look like either DWARF and/or .eh_frame information is missing.
