Hello.

Thank you for the reply. I'd like to use mold linker with gcc:
https://github.com/rui314/mold. So your solution doesn't help.

There are 2 options:
1. Add mold to -fuse-ld option
2. Implement --ld-path

The 2nd option is much more future-proof: you won't need to add new
-fuse-ld variant each time new linker comes up. To provide some
context: clang had been supporting passing path to -fuse-ld, but since
clang 12 this is deprecated in favor of new --ld-path option. I think
we should take an example from clang and implement this useful feature
in gcc as well.

Cheers,
