Revert "llvm: use proper syntax for --config option"

Browse source 
This reverts commit 577d47f3f1.

The --config= syntax with the equal sign does not work with clang 15
which is less than one year old (https://releases.llvm.org/). It does
not work with clang 14 either.

```
clang --verbose
clang version 15.0.7

clang --help | grep config

  -cl-std=<value>         OpenCL language standard to compile for.
  --config   <value>      Specifies configuration file
  --cuda-feature=<value>  Manually specify the CUDA feature to use

clang: error: unsupported option '--config=/home/runner/work/...
```

The reverted commit mentioned "issues in some situations" without
providing any example or other information.
This revert fixes the SOF fuzzer build, see more details in #61778.
