[arm-allstar] MDC1200 selective calls

[David McGough]

Hi Stephen,

I haven't tried what you're attempting. However, I wouldn't be 
surprised if you're hitting a limitation in app_rpt---that code is pretty 
basic.

I've got some MDC-1200 capable radios, I'll try to test this and extend 
app_rpt, if needed.
