On my stable/10 machines, the Fssh_ssh_malloc_init symbol is exported
by /usr/lib/private/libssh.so.5 and imported by sshd.

OTOH on my HEAD machine, the symbol is not exported by
/usr/lib/libprivatessh.so.5 and sshd does not need it.

I have no idea what happens to your build.  Try to check out the pristine
sources, perhaps.
