Allow gcc-config to execute rc

The gcc-config application uses some functions (from
/etc/init.d/functions.sh) which are simple wrappers on top of
/sbin/rc. Since this script is sourced and the functions executed
from within gcc_config_t, we allow gcc-config to execute /sbin/rc
without transitioning.
