Howdy folks,

I was hoping you could shed some light on src/ldso/aarch64/dlsym.s? As 
it's not apparent to me how this stub gets executed. I have tried a few 
things to no avail. I don't get how there is C symbols defined with the 
same name and then these defined in asm, what am I missing, it seems 
obvious...

```asm
.global dlsym
.hidden __dlsym
.type dlsym,%function
dlsym:
         mov x2,x30
         b __dlsym
```

Thanks,
Bill
