Yes, I'm a bit anxious. I didn't see that the original patch already 
included lld
should be lld [loong64].

Now when we install lld, lld-21 will be "Installing dependencies", as 
follows,

```

root at Debian-Sid:/home/ghc-9.10.3# apt install lld
Installing:
   lld

Installing dependencies:
   lld-21

   Upgrading: 0, Installing: 2, Removing: 0, Not Upgrading: 18

Continue? [Y/n] y
......
