Yes, this is easy.  If there aren't any registers, the register bits
will be disabled.  The XML version would be something like:

<!DOCTYPE target SYSTEM "gdb-target.dtd">
<target>
  <architecture>sparc:sparcv9</architecture>
  <osabi>Solaris</osabi>
</target>

The C version could be generated from that, or if you want to do it
dynamically:

  struct target_desc *result = allocate_target_description ();
  set_tdesc_architecture (result, my_bfd_arch_info_ptr);

After that, mips_linux_read_description is a simple example of how to
supply the description.

I suspect the check is going to be problematic whether we do this or
not, though.
