[Buildroot] No X11 forward in sshd

[Julianne C.]

The project is built on an x86 linux kernel (2.6.9) with X support and
SSH connectivity.  The X server is working fine and connections can be
made at will via the SSH server and client (both inbound to and
outbound from the target system).  However, the problem is that the
sshd server doesn't enable X forwarding no matter what settings are
used.  The simplest test is this (running in xterms on the X desktop
via fvwm):

1) start the sshd program:   >/usr/sbin/sshd -dd -D

2) in another window, start an ssh session to localhost: >ssh -vv -X localhost

When the sshd is built using the same configuration parameters as
contained in openssh.mk, and run in place of the existing desktop
(x86_64 Fedora 7) sshd, the X forwarding works fine, performing the
steps above.  What might be the problem with the uClibc libraries, the
X configuration or possibly the sshd configuration that would prevent
the X session from coming through.  (The xauth program was added to
the /usr/bin directory to enable the X cookies to be exchanged).
