Hi,

When we want to test the trace function that in gdb.trace directory, we 
will got a lot of UNSUPPORTED.  To use this testcase, we need follow way 
in 
http://sourceware.org/gdb/wiki/TestingGDB#Testing_gdbserver_in_a_native_configuration.

So I post a patch add some code if current target don't support trace, 
try gdbserver in tfind.exp.
If this patch goes OK.  I will post patch for other testsuite that 
support by gdbserver.

Thanks.
Hui
