faust 2.60.3+ds2-1 fails to build from source:

```
mkdir -p __tmp_llvm_lib__/libLLVMExtensions.dir && cd __tmp_llvm_lib__/libLLVMExtensions.dir && ar -x /usr/lib/llvm-16/lib/libLLVMExtensions.a
make[7]: *** No rule to make target '__tmp_llvm_lib__/libPolly.dir', needed by 'lib/libfaustwithllvm.a'. Stop.
make[7]: Leaving directory '/<<PKGBUILDDIR>>/build'
```

This has been fixed in Debian by faust/2.68.1+ds-1 release. And Noble has now latest faust/2.70.3+ds-1 which does not have this FTBFS issue.
