Great. A quick way to use an llvm tool could be:
```bash 
llvm-objdump -d -j .plt %t | grep @plt
```

This produces output similar to what `nm --synthetic` produces (when it works):
```bash
0000000000001430 <puts at plt>:
```

You'll need ofc to tweak `link_fdata` to properly parse symbol+address:

Not sure of any cleaner approach? (@yota9, @MaskRay)
