The other alternative is to configure one router as a Frame Relay switch and
not set up any Frame Relay route statements. The router configured as a
Frame Relay switch will announce via LMI the DLCI's for the PVC you want to
set up. On that router use the global "frame-relay switching" command and on
the interface connecting the other side of the back to back connection
configure "frame-relay intf-type dce" (this is what will do the magic of
announcing the DLCI and is independent of actually being a DCE interface)
and either "frame-relay map ..." or "frame-relay interface-dlci ..." with
the DLCI you want to announce. The other side you configure as normal.
Obliviously one side or the other will have to be DCE and provide clock.

Yes you can. Following is an example I've used before:
DTE side:
interface Serial1/1
no ip address
encapsulation frame-relay
no keepalive
!
interface Serial1/1.1 point-to-point
ip address 135.10.12.1 255.255.255.252
frame-relay interface-dlci 102
DCE side:
interface Serial0
no ip address
no ip directed-broadcast
encapsulation frame-relay
no ip mroute-cache
no keepalive
clockrate 64000
!
interface Serial0.1 point-to-point
ip address 135.10.12.2 255.255.255.252
no ip directed-broadcast
frame-relay interface-dlci 102
