Duh.  I have two versions of gdbserver around, won back from gdb-41.7
that I went through massive pains to get to build , and a newer one
from gdb-5.3.

Uggh.  Ok, I'll try this method(and add code to td_ta_new to dump why
its tossing TD_VERSION).  I believe that the versions have to match
since I copy the librairs from the cross-compiled toolchain into the
target's /lib directory; how they can differ isn't obvious to me.

I would have thought that building up a toolchain using Dan's
crosstool script would get me what I want.  I read the description of
solib-absolute-prefix, but it doesn't shed much light on why the
*target* is complaining.  I don't see in the remote protocol how it
can ask for a particular library, so I'll dig depper and then get back
to the mailing list.

But back to my original(and probably stupid) question.  Is there any
way to extract information(using readelf, ldd, etc) to determine the
version of the cross-built libpthread.so and libthread_db.so libraries?
