First of all don't do that.  Use solib-absolute-prefix and make a host
environment that looks like the target.  It's much more likely to work.

Second, you didn't mention until here that your target was cris.  It
just takes a couple of lines to implement multithread support in
gdbserver, but they have to be done for each port; I don't know if
anyone has done that for cris yet.  In fact gdbserver didn't support
cris until after the release of 6.3, so you should be using CVS.
