If the kernel successful found a CTF section but a symbol isn't present
in it assume it has no argument. This make ddb(4) print simpler trace
without garbage for symbols in locore:
db_enter() at db_enter+0x10
comintr(ffff800000122000) at comintr+0x2af
intr_handler(ffff80000376bc80,ffff800000121380) at intr_handler+0x6e
Xintr_legacy4_untramp() at Xintr_legacy4_untramp+0x1b3
cpu_idle_cycle() at cpu_idle_cycle+0x1b
end trace frame: 0x0, count: -5
ok?
