You cannot use the -l switch to sdcc to specify a linker script; that switch is used to add libraries to the linker files. You should be fine by using -Wl,-s,16f916.lkr (that is: -Wl to tell sdcc to pass the comma-separated list of options immediately following to the linker, -s to tell gplink that you want to specify a linker script of your own and 16f916.lkr being the name of the linker script to use). Be careful if you need to include any whitespace in the options - you'll have to quote properly. Also note that -Wl,-s,pic16f916.lkr is equivalent to -Wl,-s -Wl,pic16f916.lkr so you can split up the arguments to be passed to the linker. BUT: You probably want to use to the pic14 port (not pic16) and specify the target device using -mpic14 -p16f916 (instead of -mpic16). The pic16 backend is used for the 16-bit PICs (typically 18fxxx), pic14 is the backend for the 14-bit PICs (16fxxx and similar).
