None here.  I just checked some build logs on the 4.6 tree and
telnetd.c is definitely being compiled.  The call is there.

Can you do something like this?

XXX-rtems-nm --extern-only .../librtemsbsp.a | grep telnet

/opt/rtems-4.6/bin/mips-rtems-nm --extern-only 
/opt/rtems-4.6/mips-rtems/jmr3904/lib/librtemsbsp.a | grep telnet
telnetd.o:
000002a0 T main_telnetd
00000374 T register_telnetd
000001b8 T rtems_initialize_telnetd
00000000 T rtems_task_telnetd
00000004 D telnetd_stack_size
00000000 D telnetd_task_id
00000008 D telnetd_task_priority

So that symbol is definitely in the mips/jmr3904 I had installed.
