I'm trying to compile Whisperfish, which has a Rust crate that requires crate `bindgen` and I'm getting this error:
```
  thread 'main' panicked at /home/mersdk/.cargo/registry/src/index.crates.io-1cd66030c949c28d/bindgen-0.69.4/lib.rs:622:31:
  Unable to find libclang: "couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-*.so', 'libclang.so.*', 'libclang-*.so.*'], set the `LIBCLANG_PATH` environment variable to a path where one of these files can be found (invalid: [])"
```
There's `libclang*.so` files in build targets in `/usr/lib[64]` and in tooling in `/usr/lib`. If I do ` find / -name "libclang*"` the path gets overwritten to `/home/matti/SailfishOS/mersdk/targets/SailfishOS-4.6.0.11EA-aarch64.default/usr/lib` instead, so I guess that's where the confusion arises... And yes, I've tried to set `LIBCLANG_PATH` to any of the above in .spec, with no change.
