            Bug ID: 47540
           Summary: Overeager warning on deprecated use of `-fuse-ld=`
                    flag without even a flag to disable
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Driver

Clang recently started warning on `-fuse-ld=` with a path:
```
clang-12: warning: '-fuse-ld=' taking a path is deprecated. Use '--ld-path='
instead
```

There are still pretty widely deployed build systems using this flag construct,
and so it seems a bit frustrating for it to be enabled by default already.
Maybe wait a release or two?

Moreover, the warning could use some improvements I think. 1) It needs a flag
to disable, and 2) it would be helpful to indicate what the path was.
