Hello Again Daniel!
Sorry to all for the top post, I am stuck in OutLook land once again.
:-(
Anyway....
Yes, thank you very much Daniel, this fixed my problem!
I create a new directory on my host machine /opt/crosstool/rh62
Then I created the directories:
/opt/crosstool/rh62/lib
and
/opt/crosstool/rh62/usr/lib
Then having run ldd on my app and it's dependent libraries, I copied
over from the target to the host all of the libraries required for
running my
app:
ls /opt/crosstool/rh62/lib/
ld-linux.so.2 libc.so.6 libm.so.6 libpthread.so.0
ls /opt/crosstool/rh62/usr/lib/
libstdc++-libc6.1-2.so.3
So, as far as an entry in gdb.info, well, you can copy and paste this
email in! :-)

That's incorrect. You need matching _libraries_ - that's the libraries
used by your program, not the libraries used by GDB. The gdb client
will never look at its libthread_db.
On your target, you should have the libthread_db that came with the
libpthread you're using. On the host, you should have a complete
filesystem image of the target. Use solib-absolute-prefix to point to
it.
I really need to write a section about this in the manual.
