Subject: [PATCH] kernel: Force disable LLVM CUDA

The kernel tries to define the LINUX_COMPILER macro from the output
of `$(CC) -v | grep ' version '`, but in clang that might produce
more than one line containing ' version ' when CUDA is installed:

```
Android (8490178, based on r450784d) clang version 14.0.6
Found CUDA installation: /usr/local/cuda, version 11.0
```

That causes the macro to expand into multiple lines, upsetting the
compiler that cannot find the ending double quote.

In upstream linux this is fixed from v5.8
