Yeah. They look correct. I used the solib-absolute-prefix to point to the correct ppc lib.

The host gdb is a native gdb configured with
./configure --target=powerpc-linux --build=i686-pc-linux-gnu

Trying to debug why gdbserver segv, I ran "gdb gdbserver", "run :xxxx foo".
But doing do gdbserver runs happily. And remote debugging is possible.

I did strace on "gdb gdbserver" and "gdbserver :xxx foo". They all load the same lib. So lib should be ok here.

Is there a race condition in gdbserver in fetching thread info?
Not that I know of.  You've doublechecked that host GDB loaded the
right libpthread.so, right?
