Fix broken build for AVR and SPU targets

[Senthil Kumar Selvaraj]

The below patch fixes the build for AVR and SPU targets, which got broken
when the signature of build_function_call_vec changed. The patch passes
vNULL for the extra parameter added (arg_loc), which I hope is ok for
builtins?

If ok, could someone commit please? I don't have commit access.

        * config/avr/avr-c.c (avr_resolve_overloaded_builtin): Pass vNULL for 
arg_loc.
        * config/spu/spu-c.c (spu_resolve_overloaded_builtin): Likewise.
