working version of gdb(x86) and gdbserver(ppc)?

[Albert Ho <alberth at intellambda dot com>]

Hi,
  I wonder if anyone out there can share their remote debugging setup 
config that works.
The host is x86(P4).
The target is ppc(8270).
  Info from kernel version, gcc version, libc version, pthread library 
version is appreciated.

  I tried to have gdb and gdbserver between 2 identical machine(RH9, 
x86) without luck.
Same result as with RH9's gdb and gdb 6.0 pulled from 
www.gnu.org/software/gdb.

Then I looked into the gdb archive, played around with the 
solib-absolute-path.
Not much difference there. I even strace the lib opened by gdbserver and 
gdb.
They open different libraries. Do they suppose to open the same shared lib?

gdbserver:
open("/etc/ld.so.preload", O_RDONLY)    = -1 ENOENT (No such file or 
directory)
open("/etc/ld.so.cache", O_RDONLY)      = 3
open("/lib/tls/libthread_db.so.1", O_RDONLY) = 3
              ^^^^^^^^^^^^^^^^^
open("/lib/tls/libc.so.6", O_RDONLY)    = 3

gdb:
open("/lib/tls/libpthread.so.0", O_RDONLY) = 3
open("/lib/tls/libc.so.6", O_RDONLY)    = 7
open("/lib/ld-linux.so.2", O_RDONLY)    = 8
open("/lib/tls/libpthread.so.0", O_RDONLY) = 9
              ^^^^^^^^^^^^^^^
open("/lib/tls/libpthread-0.26.so.debug", O_RDONLY) = -1 ENOENT (No such 
file or directory)
    

Thanks
